DESCRIPTION

Each of these functions performs an in-place averaging of two matrices.

It uses the following equation:

xz[i] = (xz[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:

xz

Pointer to the first source and destination 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.
