CSROT
CSROT applies a plane rotation, where the cos and sin (c and s) are real and the vectors cx and cy are complex. jack dongarra, linpack, 3/11/78.
[in] | N | N is INTEGER On entry, N specifies the order of the vectors cx and cy. N must be at least zero. |
[in,out] | CX | CX is COMPLEX array, dimension at least ( 1 + ( N - 1 )*abs( INCX ) ). Before entry, the incremented array CX must contain the n element vector cx. On exit, CX is overwritten by the updated vector cx. |
[in] | INCX | INCX is INTEGER On entry, INCX specifies the increment for the elements of CX. INCX must not be zero. |
[in,out] | CY | CY is COMPLEX array, dimension at least ( 1 + ( N - 1 )*abs( INCY ) ). Before entry, the incremented array CY must contain the n element vector cy. On exit, CY is overwritten by the updated vector cy. |
[in] | INCY | INCY is INTEGER On entry, INCY specifies the increment for the elements of CY. INCY must not be zero. |
[in] | C | C is REAL On entry, C specifies the cosine, cos. |
[in] | S | S is REAL On entry, S specifies the sine, sin. |
