  Based on its flavor it can have vastly different implementations tailored for
  for different types of data (e.g. dense vs. sparse), different sizes of data or different operation
  optimizations.</p>
  <p>
  Note also that not all operations can be supported by all underlying implementations. If an operation is not
  supported a <a href="../../../../../../../org/apache/ignite/ml/math/exceptions/UnsupportedOperationException.html" title="class in org.apache.ignite.ml.math.exceptions"><code>UnsupportedOperationException</code></a> is thrown. This exception can also be thrown in partial cases
  where an operation is unsupported only in special cases, e.g. where a given operation cannot be deterministically
  completed in polynomial time.</p>
