zscal() void zscal ( int  n, doublecomplex  za, doublecomplex  zx[], int  incx  ) x <- ax (complex vector) (BLAS 1) Purpose This routine scales a complex vector by a complex constant. Parameters [in] n Number of elements in vector x. (If n <= 0, returns without computation) [in] za Scalar a. [in,out] zx[] Array zx[lzx] (lzx >= 1 + (n - 1)*incx) [in] Input vector x [out] Scaled vector (= ax) [in] incx Storage spacing between elements of x. (If incx <= 0, returns without computation) Reference BLAS
