Class LinearSolverAbstract

java.lang.Object

org.ejml.alg.dense.linsol.LinearSolverAbstract

All Implemented Interfaces:

LinearSolver<DenseMatrix64F>

Direct Known Subclasses:

BaseLinearSolverQrp, LinearSolverChol, LinearSolverCholLDL, LinearSolverLuBase, LinearSolverQr, LinearSolverQrHouse, LinearSolverQrHouseCol, LinearSolverQrHouseTran

public abstract class LinearSolverAbstract
extends Object
implements LinearSolver<DenseMatrix64F>

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(org.ejml.data.DenseMatrix64F) inside of its LinearSolver.setA(T) function.

Description copied from interface: LinearSolver

Computes the inverse of of the 'A' matrix passed into LinearSolver.setA(org.ejml.data.Matrix64F) 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 LinearSolver<DenseMatrix64F>

Parameters:

A_inv - Where the inverted matrix saved. Modified.
