MADlib builds Eigen using the EIGEN_MPL2_ONLY flag enabled.
From the Eigen Licensing page
(http://eigen.tuxfamily.org/index.php?title=Main_Page)
Eigen is Free Software. Starting from the 3.1.1 version, it is licensed
under the MPL2, which is a simple weak copyleft license. Common
questions about the MPL2 are answered in the official MPL2 FAQ
(http://www.mozilla.org/MPL/2.0/FAQ.html).
Note that currently, a few features rely on third-party code licensed
under the LGPL: SimplicialCholesky, AMD ordering, and constrained_cg.
Such features can be explicitly disabled by compiling with the
EIGEN_MPL2_ONLY preprocessor symbol defined.
Virtually any software may use Eigen. For example, closed-source
software may use Eigen without having to disclose its own source code.
Many proprietary and closed-source software projects are using Eigen
right now, as well as many BSD-licensed projects.

2. License Grants and Conditions
2.1. Grants
Each Contributor hereby grants You a world-wide, royalty-free,
non-exclusive license:
under intellectual property rights (other than patent or trademark)
Licensable by such Contributor to use, reproduce, make available,
modify, display, perform, distribute, and otherwise exploit its
Contributions, either on an unmodified basis, with Modifications, or as
part of a Larger Work; and

for sale, have made, import, and otherwise transfer either its
Contributions or its Contributor Version.
2.2. Effective Date
The licenses granted in Section 2.1 with respect to any Contribution
become effective for each Contribution on the date the Contributor
first distributes such Contribution.
2.3. Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights granted
under this License. No additional rights or licenses will be implied
from the distribution or licensing of Covered Software under this
License. Notwithstanding Section 2.1(b) above, no patent license is
granted by a Contributor:
for any code that a Contributor has removed from Covered Software;
or
for infringements caused by: (i) Your and any other third partys
modifications of Covered Software, or (ii) the combination of its
Contributions with other software (except as part of its Contributor
Version); or
under Patent Claims infringed by Covered Software in the absence of
its Contributions.
This License does not grant any rights in the trademarks, service
marks, or logos of any Contributor (except as may be necessary to
comply with the notice requirements in Section 3.4).
2.4. Subsequent Licenses
No Contributor makes additional grants as a result of Your choice to
distribute the Covered Software under a subsequent version of this
License (see Section 10.2) or under the terms of a Secondary License
(if permitted under the terms of Section 3.3).
2.5. Representation
Each Contributor represents that the Contributor believes its
Contributions are its original creation(s) or it has sufficient rights
to grant the rights to its Contributions conveyed by this License.
2.6. Fair Use
This License is not intended to limit any rights You have under
applicable copyright doctrines of fair use, fair dealing, or other
equivalents.
2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
in Section 2.1.
3. Responsibilities
3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients rights in the Source Code
Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
such Covered Software must also be made available in Source Code
Form, as described in Section 3.1, and You must inform recipients of
the Executable Form how they can obtain a copy of such Source Code Form
by reasonable means in a timely manner, at a charge no more than the
cost of distribution to the recipient; and
You may distribute such Executable Form under the terms of this
License, or sublicense it under different terms, provided that the
license for the Executable Form does not attempt to limit or alter the
recipients rights in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and
the Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).
3.4. Notices
You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered
by You alone, and You hereby agree to indemnify every Contributor for
any liability incurred by such Contributor as a result of warranty,
support, indemnity or liability terms You offer. You may include
additional disclaimers of warranty and limitations of liability
specific to any jurisdiction.
4. Inability to Comply Due to Statute or Regulation
If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description
must be placed in a text file included with all distributions of the
Covered Software under this License. Except to the extent prohibited
by statute or regulation, such description must be sufficiently
detailed for a recipient of ordinary skill to be able to understand it.
5. Termination
5.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a
particular Contributor are reinstated (a) provisionally, unless and
until such Contributor explicitly and finally terminates Your grants,
and (b) on an ongoing basis, if such Contributor fails to notify You
of the non-compliance by some reasonable means prior to 60 days after
You have come back into compliance. Moreover, Your grants from a
particular Contributor are reinstated on an ongoing basis if such
Contributor notifies You of the non-compliance by some reasonable
means, this is the first time You have received notice of
non-compliance with this License from such Contributor, and You become
compliant prior to 30 days after Your receipt of the notice.
5.2. If You initiate litigation against any entity by asserting a
patent infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.
5.3. In the event of termination under Sections 5.1 or 5.2 above, all
end user license agreements (excluding distributors and resellers)
which have been validly granted by You or Your distributors under this
License prior to termination shall survive termination.
6. Disclaimer of Warranty
Covered Software is provided under this License on an as is
basis, without warranty of any kind, either expressed, implied, or
statutory, including, without limitation, warranties that the Covered
Software is free of defects, merchantable, fit for a particular purpose
or non-infringing. The entire risk as to the quality and performance of
the Covered Software is with You. Should any Covered Software prove
defective in any respect, You (not any Contributor) assume the cost of
any necessary servicing, repair, or correction. This disclaimer of
warranty constitutes an essential part of this License. No use of any
Covered Software is authorized under this License except under this
disclaimer.
7. Limitation of Liability
Under no circumstances and under no legal theory, whether tort
(including negligence), contract, or otherwise, shall any Contributor,
or anyone who distributes Covered Software as permitted above, be
liable to You for any direct, indirect, special, incidental, or
consequential damages of any character including, without limitation,
damages for lost profits, loss of goodwill, work stoppage, computer
failure or malfunction, or any and all other commercial damages or
losses, even if such party shall have been informed of the possibility
of such damages. This limitation of liability shall not apply to
liability for death or personal injury resulting from such partys
negligence to the extent applicable law prohibits such limitation. Some
jurisdictions do not allow the exclusion or limitation of incidental or
consequential damages, so this exclusion and limitation may not apply
to You.
8. Litigation
Any litigation relating to this License may be brought only in the
courts of a jurisdiction where the defendant maintains its principal
place of business and such litigation shall be governed by laws of that
jurisdiction, without reference to its conflict-of-law provisions.
Nothing in this Section shall prevent a partys ability to bring
cross-claims or counter-claims.
9. Miscellaneous
This License represents the complete agreement concerning the subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent
necessary to make it enforceable. Any law or regulation which provides
that the language of a contract shall be construed against the drafter
shall not be used to construe this License against a Contributor.
10. Versions of the License
10.1. New Versions
Mozilla Foundation is the license steward. Except as provided in
Section 10.3, no one other than the license steward has the right to
modify or publish new versions of this License. Each version will be
given a distinguishing version number.
10.2. Effect of New Versions
You may distribute the Covered Software under the terms of the version
of the License under which You originally received the Covered
Software, or under the terms of any subsequent version published by the
license steward.
10.3. Modified Versions
If you create software not governed by this License, and you want to
create a new license for such software, you may create and use a
modified version of this License if you rename the license and remove
any references to the name of the license steward (except to note that
such modified license differs from this License).
10.4. Distributing Source Code Form that is Incompatible With Secondary
Licenses
If You choose to distribute Source Code Form that is Incompatible With
Secondary Licenses under the terms of this version of the License, the
notice described in Exhibit B of this License must be attached.
