Class CholeskyDecompositionInner

java.lang.Object

org.ejml.alg.dense.decomposition.chol.CholeskyDecompositionCommon

org.ejml.alg.dense.decomposition.chol.CholeskyDecompositionInner

All Implemented Interfaces:

CholeskyDecomposition<DenseMatrix64F>, DecompositionInterface<DenseMatrix64F>

public class CholeskyDecompositionInner
extends CholeskyDecompositionCommon

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 but much slower on larger matrices.
