DESCRIPTION
Each of these functions computes the average of the first source matrix
and the second source matrix and writes the output to the destination
matrix.
It uses the following equation:
z[i] = (x[i] + y[i] + 1) / 2
where i = 0, 1, ..., (m*n - 1) for real data; i = 0, 1, ..., (m*n*2 -
1) for complex data.
PARAMETERS
Each of the functions takes the following arguments:
z Pointer to the destination matrix.
x Pointer to the first source matrix.
y Pointer to the second source matrix.
m Number of rows in the matrices.
n Number of columns in the matrices.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it
returns MLIB_FAILURE.
