| This class centralizes in one place some of the most commonly used functions this package. |
| The <code>MathTransforms</code> class provides the following services: |
| |

| <li>Create various SIS implementations of <a href="http://www.geoapi.org/3.0/javadoc/org.opengis.geoapi/org/opengis/referencing/operation/MathTransform.html" title="class or interface in org.opengis.referencing.operation" class="external-link"><code>MathTransform</code></a>.</li> |
| <li>Perform non-standard operations on arbitrary instances.</li> |
| </ul> |
| |
| The factory static methods are provided as convenient alternatives to the GeoAPI <a href="http://www.geoapi.org/3.0/javadoc/org.opengis.geoapi/org/opengis/referencing/operation/MathTransformFactory.html" title="class or interface in org.opengis.referencing.operation" class="external-link"><code>MathTransformFactory</code></a> |

| GeoAPI factory interfaces instead.</div> |

| <div class="block">A buckle method for calculating derivative and coordinate transformation in a single step. |
| The transform result is stored in the given destination array, and the derivative matrix |
| is returned. Invoking this method is equivalent to the following code, except that it may |
| execute faster with some <code>MathTransform</code> implementations: |
