All Implemented Interfaces:

public class CholeskyDecompositionInner_D64
extends CholeskyDecompositionCommon_D64

This implementation of a Cholesky decomposition using the inner-product form. For large matrices a block implementation is better. On larger matrices the lower triangular decomposition is significantly faster. This is faster on smaller matrices than CholeskyDecompositionBlock_D64 but much slower on larger matrices.
