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
The kernel of a matrix with n columns is a linear subspace of n-dimensional Euclidean space. |
| LU |
Use the LU decomposition to solve Ax = b
where A is square and det(A) ! |
| OLSSolver |
This class solves a system of over-determined linear equations in the ordinary least square sense. |
| Solver |
Solve a system of linear equations in the form:
Ax = b,
where A has #rows <= #columns. |
