org.ejml.dense.row.linsol.LinearSolverAbstract_ZDRM

All Implemented Interfaces:

LinearSolver<ZMatrixRMaj,ZMatrixRMaj>, LinearSolverDense<ZMatrixRMaj>

public abstract class LinearSolverAbstract_ZDRM
extends Object
implements LinearSolverDense<ZMatrixRMaj>

An abstract class that provides some common functionality and a default implementation of invert that uses the solve function of the child class.

The extending class must explicity call _setA(ZMatrixRMaj) inside of its LinearSolver.setA(S) function.

Description copied from interface: LinearSolverDense

Computes the inverse of of the 'A' matrix passed into LinearSolver.setA(Matrix) and writes the results to the provided matrix. If 'A_inv' needs to be different from 'A' is implementation dependent.

Specified by:

invert in interface LinearSolverDense<ZMatrixRMaj>

Parameters:

A_inv - Where the inverted matrix saved. Modified.
