Method Summary

Modifier and Type	Method and Description
static AMatrix	solve(AMatrix A, AMatrix B) A general linear system solver, For a matrix A, returns a matrix whose each column is the solution to the equation A.x = b, where b is the corresponding column of B.
static AVector	solve(AMatrix A, AVector b) A general linear system solver, Returns the solution to the equation A.x = b, returns null if A is square and has no unique solution.
static AMatrix	solveLeastSquares(AMatrix A, AMatrix B) Returns the least squares solution to the equation A.X = B Use this in the case of over-determined (more equations than unknowns) or under-determined (more unknowns than equations)
static AVector	solveLeastSquares(AMatrix A, AVector b) Returns the least squares solution to the equation A.x = b Use this in the case of over-determined (more equations than unknowns) or under-determined (more unknowns than equations)
