Functions for managing matrices
The following functions are used to manage the matrices:
MatAddAdds two matrices of same dimensions (same number of rows and same number of columns).
MatCopyCreates the copy of a matrix.
MatCreateCreates a matrix containing 0 row and 0 column.
MatDeleteDeletes an existing matrix.
MatDeterminantCalculates the determinant of a square matrix (the number of rows is equal to the number of columns).
MatErrorIdentifies the type of the last error caused by a Matxxx function (functions for matrix management).
MatExistChecks the existence of a matrix in memory.
MatFillInitializes all the elements found in a matrix of a given size.
MatFloatAddAdds a value to each matrix element.
MatFloatMultiplyMultiplies each matrix element by a value.
MatInvertReverses a square matrix.
MatMultiplyMultiplies two matrices.
MatNbColumnReturns the number of columns found in a matrix.
MatNbLineReturns the number of rows found in a matrix.
MatReadReads the value of a matrix element.
MatReadColumnReads the value of all the elements found in a matrix column.
MatReadLineReads the value of all elements found in a matrix row.
MatStackCompresses the memory footprint occupied by a matrix.
MatTransposeCalculates the transposed matrix.
MatWriteWrites an element into a matrix.
