Each of these functions performs an in-place multiplication of a matrix by a scalar and then adds an offset. For real data, the following equation is used: xz[i] = a[0]*xz[i] + b[0] where i = 0, 1, ..., (m*n - 1). For complex data, the following equation is used: tmp = xz[2*i] xz[2*i] = a[0]*tmp - a[1]*xz[2*i + 1] + b[0] xz[2*i + 1] = a[1]*tmp + a[0]*xz[2*i + 1] + b[1] where i = 0, 1, ..., (m*n - 1). PARAMETERS
Each of the functions takes the following arguments: xz Pointer to the source and destination matrix. a Pointer to the source scaling factor. When the function is used with complex data types, a[0] contains the scalar for the real part, and a[1] contains the scalar for the imaginary part. b Pointer to the source offset. When the function is used with complex data types, b[0] contains the offset for the real part, and b[1] contains the offset for the imaginary part. m Number of rows in the matrix. n Number of columns in the matrix. RETURN VALUES
Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE. ATTRIBUTES
