csrot Apply a plane rotation, where the cos and sin (c and s) are real and the vectors x and y are complex.
-
* 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)
-
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 (output)
-
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.
-
* C (input)
-
On entry, the cosine.
-
* S (input)
-
On entry, the sin.
