csrscl

csrscl.f(3)							      LAPACK							       csrscl.f(3)

NAME

       csrscl.f -

SYNOPSIS

   Functions/Subroutines
       subroutine csrscl (N, SA, SX, INCX)
	   CSRSCL multiplies a vector by the reciprocal of a real scalar.

Function/Subroutine Documentation
   subroutine csrscl (integerN, realSA, complex, dimension( * )SX, integerINCX)
       CSRSCL multiplies a vector by the reciprocal of a real scalar.

       Purpose:

	    CSRSCL 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.

       Parameters:
	   N

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

	   SA

		     SA is 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

		     SX 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 SX.
		     > 0:  SX(1) = X(1) and SX(1+(i-1)*INCX) = x(i),	 1< i<= n
