NAME

SRC/lapack_64_obj/crscl.f

SYNOPSIS

Functions/Subroutines


subroutine CRSCL (n, a, x, incx)
CRSCL multiplies a vector by the reciprocal of a real scalar.

Function/Subroutine Documentation

subroutine CRSCL (integer n, complex a, complex, dimension( * ) x, integer incx)

CRSCL multiplies a vector by the reciprocal of a real scalar.

Purpose:

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

Parameters

N 

!>          N is INTEGER
!>          The number of components of the vector x.
!>

A

!>          A is COMPLEX
!>          The scalar a which is used to divide each component of x.
!>          A must not be 0, or the subroutine will divide by zero.
!>

X

!>          X is COMPLEX array, dimension
!>                         (1+(N-1)*abs(INCX))
!>          The n-element vector x.
!>

INCX

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