DESCRIPTION
Each of these functions performs an in-place multiplication of two vectors and shifts the result.
For real data, the following equation is used:
xz[i] = xz[i] * y[i] * 2**(-shift)
where i = 0, 1, ..., (n - 1).
For complex data, the following equation is used:
tmp = xz[2*i]
xz[2*i] = (tmp*y[2*i] - xz[2*i + 1]*y[2*i + 1]) * 2**(-shift)
xz[2*i + 1] = (tmp*y[2*i + 1] + xz[2*i + 1]*y[2*i]) * 2**(-shift)
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 result vector.
y Pointer to the first element of the second source vector.
n Number of elements in each vector.
shift Right shifting factor. The ranges of valid shift are:
1 <= shift <= 8 for U8, S8, U8C, S8C types
1 <= shift <= 16 for S16, S16C types
1 <= shift <= 31 for S32, S32C types
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
