/**
* An interface to classes that implement an algorithm to calculate the
* Cholesky decomposition of a real symmetric positive-definite matrix.
+ * <p>The Cholesky decomposition of a real symmetric positive-definite
+ * matrix A consists of a lower triangular matrix L with same size that
+ * satisfy: A = LL<sup>T</sup>Q = I). In a sense, this is the square root of
A.</p>
* <p>This interface is based on the class with similar name from the
* <a href="http://math.nist.gov/javanumerics/jama/";>JAMA</a> library, with the
* following changes:</p>
