# srscl(3lapack)

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

## NAME

SRSCL - multiplies an n-element real vector x by the real scalar 1/a

## SYNOPSIS

- SUBROUTINE SRSCL(

  N, SA, SX, INCX )

- INTEGER

  INCX, N

- REAL

  SA

- REAL

  SX( \* )

## PURPOSE

SRSCL multiplies an n-element real 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) REAL

  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) REAL 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
