NAME srot - Apply a Given's rotation constructed by SROTG. SYNOPSIS SUBROUTINE SROT (N, X, INCY, Y, INCY, C, S) INTEGER INCX, INCY, N REAL C, S, X( * ), Y( * ) #include <sunperf.h> void srot(int n, float *sx, int incx, float *sy, int incy, float c, float s) ; PURPOSE SROT - Apply a Given's rotation constructed by SROTG. PARAMETERS N - INTEGER. On entry, N specifies the number of elements in the vector. N must be at least one for the sub- routine to have any visible effect. Unchanged on exit. X - REAL array of DIMENSION at least ( 1 + ( n - 1 )*abs( INCX ) ). Before entry, the incremented array X must contain the vector x. Unchanged on exit. INCX - INTEGER. On entry, INCX specifies the increment for the elements of X. INCX must not be zero. Unchanged on exit. Y - REAL array of DIMENSION at least ( 1 + ( m - 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 - INTEGER. On entry, INCY specifies the increment for the elements of Y. INCY must not be zero. Unchanged on exit. C, S - REAL On entry, the rotation values con- structed by SROTG. Unchanged on exit.
