NAME
mlib_VectorMulMShift_S16_S16_Mod, mlib_VectorMulMShift_S16_S16_Sat, mlib_VectorMulMShift_S16C_S16C_Mod, mlib_VectorMulMShift_S16C_S16C_Sat - multiplication of vector by matrix with shifting
SYNOPSIS
cc [ flag... ] file... -lmlib [ library... ] #include <mlib.h> mlib_status mlib_VectorMulMShift_S16_S16_Mod(mlib_s16 *z, const mlib_s16 *x, const mlib_s16 *y, mlib_s32 m, mlib_s32 n, mlib_s32 shift); mlib_status mlib_VectorMulMShift_S16_S16_Sat(mlib_s16 *z, const mlib_s16 *x, const mlib_s16 *y, mlib_s32 m, mlib_s32 n, mlib_s32 shift); mlib_status mlib_VectorMulMShift_S16C_S16C_Mod(mlib_s16 *z, const mlib_s16 *x, const mlib_s16 *y, mlib_s32 m, mlib_s32 n, mlib_s32 shift); mlib_status mlib_VectorMulMShift_S16C_S16C_Sat(mlib_s16 *z, const mlib_s16 *x, const mlib_s16 *y, mlib_s32 m, mlib_s32 n, mlib_s32 shift);
DESCRIPTION
Each of these functions multiplies a vector by a matrix and shifts the results. For real data, the following equation is used: m-1 z[i] = { SUM (x[j] * y[j*m + i]) } * 2**(-shift) j=0 where i = 0, 1, ..., (n - 1). For complex data, the following equation is used: m-1 z[2*i ] = { SUM (xR*yR - xI*yI) } * 2**(-shift) j=0 m-1 z[2*i + 1] = { SUM (xR*yI + xI*yR) } * 2**(-shift) j=0 where i = 0, 1, ..., (n - 1), and xR = x[2*j] xI = x[2*j + 1] yR = y[2*(j*m + i)] yI = y[2*(j*m + i) + 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. y Pointer to the first element of the source matrix. m Number of rows in the matrix, and number of elements in the source vector. n Number of columns in the matrix, and number of elements in the destination vector. shift Right shifting factor.
RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
