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.
