DESCRIPTION
Each of these functions computes an in-place multiplication of a vector by a scalar and adds the result to another vector.
For real data, the following equation is used:
xz[i] = xz[i] + y[i]*c[0]
where i = 0, 1, ..., (n - 1).
For complex data, the following equation is used:
xz[2*i] = xz[2*i] + y[2*i]*c[0] - y[2*i + 1]*c[1]
xz[2*i + 1] = xz[2*i + 1] + y[2*i]*c[1] + y[2*i + 1]*c[0]
where i = 0, 1, ..., (n - 1).
PARAMETERS
Each of the functions takes the following arguments:
xz Pointer to the first element of the first source and destination vector.
y Pointer to the first element of the second source vector.
c Pointer to the source scalar. When the function is used with complex data types, c[0] contains the real part of the
scalar, and c[1] contains the imaginary part of the scalar.
n Number of elements in the vectors.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
