BaseDecomposition_FDRB_to_FDRM

public BaseDecomposition_FDRB_to_FDRM(DecompositionInterface<FMatrixRBlock> alg,

Method Detail

decompose

public boolean decompose(FMatrixRMaj A)

Description copied from interface: DecompositionInterface

Computes the decomposition of the input matrix. Depending on the implementation the input matrix might be stored internally or modified. If it is modified then the function DecompositionInterface.inputModified() will return true and the matrix should not be modified until the decomposition is no longer needed.

Specified by:

decompose in interface DecompositionInterface<FMatrixRMaj>

Parameters:

A - The matrix which is being decomposed. Modification is implementation dependent.

Returns:

Returns if it was able to decompose the matrix.

convertBlockToRow

public void convertBlockToRow(int numRows,
                              int numCols,
                              int blockLength,
                              float[] data)

inputModified

public boolean inputModified()

Description copied from interface: DecompositionInterface

Is the input matrix to DecompositionInterface.decompose(org.ejml.data.Matrix) is modified during the decomposition process.

Specified by:

inputModified in interface DecompositionInterface<FMatrixRMaj>

Returns:

true if the input matrix to decompose() is modified.
