refmatrix: Matrix to Row Echelon Form
In cmna: Computational Methods for Numerical Analysis

Description Usage Arguments Details Value See Also Examples

Transform a matrix to row echelon form.

refmatrix(m)

rrefmatrix(m)

solvematrix(A, b)

`m`	a matrix
`A`	a square matrix representing the coefficients of a linear system in `solvematrix`
`b`	a vector representing the right-hand side of the linear system in `solvematrix`

refmatrix reduces a matrix to row echelon form. This is not a reduced row echelon form, though that can be easily calculated from the diagonal. This function works on non-square matrices.

rrefmatrix returns the reduced row echelon matrix.

solvematrix solves a linear system using rrefmatrix.

the modified matrix
