Functions for managing matrices
The following functions are used to manage the matrices:
 MatAdd Adds two matrices of same dimensions (same number of rows and same number of columns). MatCopy Creates the copy of a matrix. MatCreate Creates a matrix containing 0 row and 0 column. MatDelete Deletes an existing matrix. MatDeterminant Calculates the determinant of a square matrix (the number of rows is equal to the number of columns). MatError Identifies the type of the last error caused by a Matxxx function (functions for matrix management). MatExist Checks the existence of a matrix in memory. MatFill Initializes all the elements found in a matrix of a given size. MatFloatAdd Adds a value to each matrix element. MatFloatMultiply Multiplies each matrix element by a value. MatInvert Inverts a square matrix. MatMultiply Multiplies two matrices. MatNbColumn Returns the number of columns found in a matrix. MatNbLine Returns the number of rows found in a matrix. MatRead Reads the value of a matrix element. MatReadColumn Reads the value of all the elements found in a matrix column. MatReadLine Reads the value of all elements found in a matrix row. MatStack Compresses the memory footprint occupied by a matrix. MatTranspose Calculates the transposed matrix. MatWrite Writes an element into a matrix.
