Description

DETP is a numeric method for the determinant's calculation that indirectly uses the formula that can be visualized in the MATLAB with de help command. Now with new functions:
Linear equations system, equation of a plane, matrix inverse and UL factorization.
I would like to divulge this interesting numeric relationship!

MATLAB release MATLAB 6.5 (R13)

Simplification of the code and additional information

08 Feb 2008

New functions (with pivoting):
-Linear equations system;
-Equation of a plane using determinant;
-Matrix inverse.

13 Feb 2008

New function: UL factorization.
Returns upper triangular matrix U, lower triangular matrix L and permutation matrix P so that U*L=A*P.
