SYNOPSIS SUBROUTINE DROT(N, X, INCX, Y, INCY, C, S) INTEGER N, INCX, INCY DOUBLE PRECISION C, S DOUBLE PRECISION X(*), Y(*) SUBROUTINE DROT_64(N, X, INCX, Y, INCY, C, S) INTEGER*8 N, INCX, INCY DOUBLE PRECISION C, S DOUBLE PRECISION X(*), Y(*) F95 INTERFACE SUBROUTINE ROT(N, X, INCX, Y, INCY, C, S) INTEGER :: N, INCX, INCY REAL(8) :: C, S REAL(8), DIMENSION(:) :: X, Y SUBROUTINE ROT_64(N, X, INCX, Y, INCY, C, S) INTEGER(8) :: N, INCX, INCY REAL(8) :: C, S REAL(8), DIMENSION(:) :: X, Y C INTERFACE #include <sunperf.h> void drot(int n, double *x, int incx, double *y, int incy, double c, double s); void drot_64(long n, double *x, long incx, double *y, long incy, double c, double s); PURPOSE drot Apply a Given's rotation constructed by SROTG. ARGUMENTS N (input) On entry, N specifies the number of elements in the vector. N must be at least one for the subroutine to have any visible effect. Unchanged on exit. X (input/output) ( 1 + ( N - 1 )*abs( INCX ) ). On entry, the incremented array X must contain the vector x. On exit, X is overwritten by the updated vector x. INCX (input) On entry, INCX specifies the increment for the elements of X. Unchanged on exit. Y (input/output) ( 1 + ( N - 1 )*abs( INCY ) ). On entry, the incremented array Y must contain the vector y. On exit, Y is overwritten by the updated vector y. INCY (input) On entry, INCY specifies the increment for the elements of Y. Unchanged on exit. C (input) On entry, the C rotation value constructed by SROTG. Unchanged on exit. S (input) On entry, the S rotation value constructed by SROTG. Unchanged on exit. 7 Nov 2015 drot(3P)
