Each of these functions performs a multiplication of two vectors, shifts the result, and puts it into a third vector. For real data, the following equation is used: z[i] = x[i] * y[i] * 2**(-shift) 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]) * 2**(-shift) z[2*i + 1] = (x[2*i]*y[2*i + 1] + x[2*i + 1]*y[2*i]) * 2**(-shift) where i = 0, 1, ..., (n - 1). PARAMETERS
Each of the functions takes the following arguments: z Pointer to the first element of the result 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 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. ATTRIBUTES
