Program Definition

This program performs different Numerical Methods computations on solving the value of X, Yand Z, the determinant and also the inverse matrix of linear and non-linear equations, such as Elementary

perations, !oolittle"s Method, #tandard Method, #ecant Method and $auss" #iedel Method%
