Each of these functions performs an in-place multiplication of a vector by a scalar and shifts the result. For real data, the following equation is used: xz[i] = xz[i] * c[0] * 2**(-shift) where i = 0, 1, ..., (n - 1). For complex data, the following equation is used: tmp = xz[2*i] xz[2*i] = (tmp*c[0] - xz[2*i + 1]*c[1]) * 2**(-shift) xz[2*i + 1] = (tmp*c[1] + xz[2*i + 1]*c[0]) * 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 source and result 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 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
