CLACRT performs a linear transformation of a pair of complex vectors.
Download CLACRT + dependencies [TGZ] [ZIP] [TXT]
CLACRT performs the operation ( c s )( x ) ==> ( x ) ( -s c )( y ) ( y ) where c and s are complex and the vectors x and y are complex.
[in] | N | N is INTEGER The number of elements in the vectors CX and CY. |
[in,out] | CX | CX is COMPLEX array, dimension (N) On input, the vector x. On output, CX is overwritten with c*x + s*y. |
[in] | INCX | INCX is INTEGER The increment between successive values of CX. INCX <> 0. |
[in,out] | CY | CY is COMPLEX array, dimension (N) On input, the vector y. On output, CY is overwritten with -s*x + c*y. |
[in] | INCY | INCY is INTEGER The increment between successive values of CY. INCY <> 0. |
[in] | C | C is COMPLEX |
[in] | S | S is COMPLEX C and S define the matrix [ C S ]. [ -S C ] |
