Class ComplexLstsqSolver

java.lang.Object

org.flag4j.linalg.solvers.lstsq.LstsqSolver<CMatrix,CVector>

org.flag4j.linalg.solvers.lstsq.ComplexLstsqSolver

All Implemented Interfaces:

LinearMatrixSolver<CMatrix,CVector>, LinearSolver<CMatrix>

public class ComplexLstsqSolver
extends LstsqSolver<CMatrix,CVector>

This class solves a linear system of equations Ax=b in a least-squares sense.

That is, minimizes ||Ax-b||₂ which is equivalent to solving the normal equations A^HAx=A^Hb. This is done using efficiently a QR decomposition.
