NAME
     crotg - Construct a Given's plane rotation

SYNOPSIS
     SUBROUTINE CROTG (A, B, C, S)

     COMPLEX    A, B, S REAL       C



     #include <sunperf.h>

     void crotg(complex *ca, complex *cb, float *sc, complex  *s)
               ;

PURPOSE
     CROTG - Construct a Given's plane rotation that will annihi-
     late an element of a vector.


PARAMETERS
     A         - COMPLEX.
               On entry, A contains the entry in the first vector
               that  corresponds to the element to be annihilated
               in the second vector.  Unchanged on exit.

     B         - COMPLEX.
               On entry, B contains the entry to  be  annihilated
               in the second vector.

     C         - REAL.
               On exit, C and S are the elements of the  rotation
               matrix that will be applied to annihilate B.

     S         - COMPLEX.
               On exit, C and S are the elements of the  rotation
               matrix that will be applied to annihilate B.
