Method Detail

invert

public final MatrixStore<Double> invert(MatrixStore<Double> original)
                                 throws TaskException

Description copied from interface: InverterTask

The output must be a "right inverse" and a "generalised inverse".

Specified by:

invert in interface InverterTask<Double>

Throws:

TaskException

BasicMatrix.invert()

preallocate

public final DecompositionStore<Double> preallocate(Access2D<Double> template)

Description copied from interface: InverterTask

Implementiong this method is optional.

Will create a DecompositionStore instance suitable for use with #solve(Access2D, DecompositionStore). When solving an equation system [A][X]=[B] ([mxn][nxb]=[mxb]) the preallocated memory/matrix will typically be either mxb or nxb (if A is square then there is no doubt).

Specified by:

preallocate in interface InverterTask<Double>

Returns:
