Abstract

A simple and direct process is derived to compute the determinant of any square matrix of high order. The approach involves successive applying the matrix order condensation algorithm.  A computer program listing in MATLAB is included and examples for finding the determinant of a given 7x7 matrix are given here for illustration.
