srotm Apply a Given's rotation constructed by SROTMG.
-
* 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)
-
( 1 + ( n - 1 )*abs( INCX ) ).
Before entry, the incremented array X must contain the
vector x.
Unchanged on exit.
-
* INCX (input)
-
On entry, INCX specifies the increment for the elements of
X. INCX must not be zero.
Unchanged on exit.
-
* Y (input/output)
-
( 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 (input)
-
On entry, INCY specifies the increment for the elements of
Y. INCY must not be zero.
Unchanged on exit.
-
* PARAM (input)
-
On entry, the rotation values constructed by SROTMG. Unchanged on exit.
