DESCRIPTION

Each of these functions multiplies one vector by another vector.

For real data, the following equation is used:

z[i] = x[i] * y[i]

where i = 0, 1, ..., (n - 1).

For complex data, the following equation is used:

z[2*i]     = x[2*i]*y[2*i] - x[2*i + 1]*y[2*i + 1]
z[2*i + 1] = x[2*i]*y[2*i + 1] + x[2*i + 1]*y[2*i]

where i = 0, 1, ..., (n - 1).  

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.
