DESCRIPTION

Each of these functions computes the average of two vectors.

It uses the following equation:

z[i] = (x[i] + y[i] + 1) / 2

where i = 0, 1, ..., (n - 1) for real data; i = 0, 1, ..., (2*n - 1) for complex data.  

PARAMETERS

Each of the functions takes the following arguments:

z

Pointer to the first element of the destination vector.

x

Pointer to the first element of the first source vector.

y

Pointer to the first element of the second source vector.

n

Number of elements in the vectors.

 

RETURN VALUES

Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
