NAME

CSRSCL - multiplie an n-element complex vector x by the

real scalar 1/a

SYNOPSIS

SUBROUTINE CSRSCL( N, SA, SX, INCX )
    INTEGER        INCX, N
    REAL           SA
    COMPLEX        SX( * )

PURPOSE

CSRSCL multiplies an n-element complex vector x by the re

al 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) REAL

The scalar a which is used to divide each compo

nent of x. SA must be >= 0, or the subroutine will divide by ze

ro.

SX (input/output) COMPLEX 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
