DESCRIPTION
Each of these functions scales a vector by multiplying by a scalar and adding an offset.
For real data, the following equation is used:
z[i] = a[0]*x[i] + b[0]
where i = 0, 1, ..., (n - 1).
For complex data, the following equation is used:
z[2*i] = a[0]*x[2*i] - a[1]*x[2*i + 1] + b[0]
z[2*i + 1] = a[1]*x[2*i] + a[0]*x[2*i + 1] + b[1]
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 source vector.
a Pointer to the source scaling factor. When the function is used with complex data types, a[0] contains the real part of
the scaling factor, and a[1] contains the imaginary part of the scaling factor.
b Pointer to the source offset. When the function is used with complex data types, b[0] contains the real part of the off-
set, and b[1] contains the imaginary part of the offset.
n Number of elements in the vectors.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
