Matrix management functions
The following functions are used to manage 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 whether the matrix exists 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 | Calculates the inverse of 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. |
