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 SX is REAL array, dimension N double precision vector with N elements INCX INCX is INTEGER storage spacing between elements of 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 Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
