# zsrscl(3)

multiplie an n-element complex vector x by the real scalar 1/a

## NAME

ZSRSCL - multiplie an n-element complex vector x by the real scalar 1/a

## SYNOPSIS

- SUBROUTINE ZDRSCL(

  N, SA, SX, INCX )

- INTEGER

  INCX, N

- DOUBLE

  PRECISION SA

- COMPLEX\*16

  SX( \* )

## PURPOSE

CDRSCL multiplies an n-element complex vector x by the real scalar 1/a.  This is done without overflow or underflow as long as the final result x/a does not overflow or underflow.\

## ARGUMENTS

- N (input) INTEGER

  The number of components of the vector x.

- SA (input) DOUBLE PRECISION

  The scalar a which is used to divide each component of x. SA must be \>= 0, or the subroutine will divide by zero.

- SX (input/output) COMPLEX\*16 array, dimension

  (1+(N-1)\*abs(INCX)) The n-element vector x.

- INCX (input) INTEGER

  The increment between successive values of the vector SX. \> 0:  SX(1) = X(1) and SX(1+(i-1)\*INCX) = x(i),     1\< i\<= n\
   \< 0:  SX(1) = X(n) and SX(1+(i-1)\*INCX) = x(n-i+1), 1\< i\<= n
