As shipped in IRIX 6.5. First release of IRIX 6.5.
NAME CSROT - CSROT applies the complex Givens rotation (X) ( C S)(X) (Y) = (-S C)(Y) N times where for I = 0,...,N-1 X = CX(1+I*INCX) Y = CY(1+I*INCY) SYNOPSYS SUBROUTINE CSROT(N,CX,INCX,CY,INCY,C,S) DESCRIPTION Argument Description N (integer) number of elements in each vector CX (complex array) beginning of one vector INCX (integer) memory spacing of successive elements of vector CX CY (complex array) beginning of the other vector INCY (integer) memory spacing of successive elements of vector CY C (real) cosine term of the rotation S (real) sine term of the rotation.
