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.
