org.ejml.dense.row.decomposition.chol.CholeskyDecompositionCommon_DDRM

org.ejml.dense.row.decomposition.chol.CholeskyDecompositionInner_DDRM

All Implemented Interfaces:

org.ejml.interfaces.decomposition.CholeskyDecomposition<org.ejml.data.DMatrixRMaj>, org.ejml.interfaces.decomposition.CholeskyDecomposition_F64<org.ejml.data.DMatrixRMaj>, org.ejml.interfaces.decomposition.DecompositionInterface<org.ejml.data.DMatrixRMaj>

public class CholeskyDecompositionInner_DDRM
extends CholeskyDecompositionCommon_DDRM

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_DDRM but much slower on larger matrices.
