Interface Summary

LinearSystemSolver.Solution

This is the solution to a linear system of equations.

Class Summary

BackwardSubstitution	Backward substitution solves a matrix equation in the form Ux = b by an iterative process for an upper triangular matrix U.
ForwardSubstitution	Forward substitution solves a matrix equation in the form Lx = b by an iterative process for a lower triangular matrix L.
Kernel	The kernel or null space (also nullspace) of a matrix A is the set of all vectors x for which Ax = 0.
LinearSystemSolver	Solve a system of linear equations in the form: Ax = b, We assume that, after row reduction, A has no more rows than columns.
LSProblem	This is the problem of solving a system of linear equations.
LUSolver	Use LU decomposition to solve Ax = b where A is square and det(A) != 0.
OLSSolver	This class solves an over-determined system of linear equations in the ordinary least square sense.
OLSSolverByQR	This class solves an over-determined system of linear equations in the ordinary least square sense.
OLSSolverBySVD	This class solves an over-determined system of linear equations in the ordinary least square sense.
