public CholeskyDecomposition_B64_to_D64(boolean lower)

Method Detail

isLower

public boolean isLower()

Description copied from interface: CholeskyDecomposition

If true the decomposition was for a lower triangular matrix. If false it was for an upper triangular matrix.

Specified by:

isLower in interface CholeskyDecomposition<DenseMatrix64F>

Returns:

True if lower, false if upper.

getT

public DenseMatrix64F getT(DenseMatrix64F T)

Description copied from interface: CholeskyDecomposition

Returns the triangular matrix from the decomposition.

If an input is provided that matrix is used to write the results to. Otherwise a new matrix is created and the results written to it.

Specified by:

getT in interface CholeskyDecomposition<DenseMatrix64F>

Parameters:

T - If not null then the decomposed matrix is written here.

Returns:

A lower or upper triangular matrix.
