 Addition
 --------
 MatAddI%
 MatAddL%
 MatAddS%
 MatAddD%
 MatAddC%
 Finds the sum of two matrixes whose row and column dimensions are identical.


 Subtraction
 -----------
 MatSubI%
 MatSubL%
 MatSubS%
 MatSubD%
 MatSubC%
 Finds the difference between two matrixes whose row and column dimensions
 are identical.


 Multiplication
 --------------
 MatMultI%
 MatMultL%
 MatMultS%
 MatMultD%
 MatMultC%
 Finds the product of two matrixes where the first matrix has the same number
 of columns as the second matrix has rows.


 Determinant
 -----------
 MatDetI%
 MatDetL%
 MatDetS%
 MatDetD%
 MatDetC%
 Finds the determinant of a square matrix.


 Inverse
 -------
 MatInvS%
 MatInvD%
 MatInvC%
 Finds the multiplicative inverse of a square matrix, if one exists; that is,
 if the determinant is not equal
 to 0.


 Gaussian elimination
 --------------------
 MatSEqnS%
 MatSEqnD%
 MatSEqnC%
 Uses Gaussian elimination to solve, if a solution exists, a system of linear
 equations contained in a square matrix and a vector.
