NAME
       srotm.f -

SYNOPSIS
   Functions/Subroutines
       subroutine srotm (N, SX, INCX, SY, INCY, SPARAM)
	   SROTM

Function/Subroutine Documentation
   subroutine srotm (integerN, real, dimension(*)SX, integerINCX, real, dimension(*)SY,
       integerINCY, real, dimension(5)SPARAM)
       SROTM Purpose:

	       APPLY THE MODIFIED GIVENS TRANSFORMATION, H, TO THE 2 BY N MATRIX

	       (SX**T) , WHERE **T INDICATES TRANSPOSE. THE ELEMENTS OF SX ARE IN
	       (SX**T)

	       SX(LX+I*INCX), I = 0 TO N-1, WHERE LX = 1 IF INCX .GE. 0, ELSE
	       LX = (-INCX)*N, AND SIMILARLY FOR SY USING USING LY AND INCY.
	       WITH SPARAM(1)=SFLAG, H HAS ONE OF THE FOLLOWING FORMS..

	       SFLAG=-1.E0     SFLAG=0.E0	 SFLAG=1.E0	SFLAG=-2.E0

		 (SH11	SH12)	 (1.E0	SH12)	 (SH11	1.E0)	 (1.E0	0.E0)
	       H=(	    )	 (	    )	 (	    )	 (	    )
		 (SH21	SH22),	 (SH21	1.E0),	 (-1.E0 SH22),	 (0.E0	1.E0).
	       SEE  SROTMG FOR A DESCRIPTION OF DATA STORAGE IN SPARAM.

       Parameters:
	   N

		     N is INTEGER
		    number of elements in input vector(s)

	   SX

	   SY

		     SY is REAL array, dimension N
		    double precision vector with N elements

	   INCY

		     INCY is INTEGER
		    storage spacing between elements of SY

	   SPARAM

		     SPARAM is REAL array, dimension 5
		SPARAM(1)=SFLAG
		SPARAM(2)=SH11
		SPARAM(3)=SH21
		SPARAM(4)=SH12
		SPARAM(5)=SH22
