DESCRIPTION
Each of these functions finds the maximum value of all elements in a matrix.
It uses the following equation:
max[0] = MAX{ x[i] i = 0, 1, ..., (m*n - 1) }
PARAMETERS
Each of the functions takes the following arguments:
max Pointer to the maximum value.
x Pointer to the first element of the source matrix.
m Number of rows in the source matrix.
n Number of columns in the source matrix.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
