CSSCAL(3) BLAS routine of NEC Numeric Library Collection CSSCAL(3) NAME CSSCAL - BLAS level one, Scales a complex vector SYNOPSIS SUBROUTINE CSSCAL ( n, alpha, x, incx ) INTEGER n, incx COMPLEX x REAL alpha DESCRIPTION CSSCAL scales a complex vector with a real scalar. CSSCAL scales the vector x of length n and increment incx by the constant alpha. Ths routine performs the following vector operation: x <-- alpha x where alpha is a real scalar, and x is a complex vector. ARGUMENTS n INTEGER. (input) Number of elements in the vector. If n <= 0, this routine returns without computation. alpha REAL. (input) Value used to scale vector x COMPLEX. (input and output) Array of dimension (n-1) * abs(incx) + 1. Vector to be scaled. incx INTEGER. (input) Increment between elements of x. If incx = 0, the results will be unpredictable. NOTES This routine is Level 1 Basic Linear Algebra Subprograms (Level 1 BLAS). When working backward (incx < 0 or incy < 0), each routine starts at the end of the vector and moves backward, as follows: x(1-incx * (n-1)), x(1-incx * (n-2)), ..., x(1) BLAS routine CSSCAL(3)
