NAME
       zgerc - perform the rank 1 operation   A := alpha*x*conjg( y' ) + A

SYNOPSIS
       SUBROUTINE ZGERC(M, N, ALPHA, X, INCX, Y, INCY, A, LDA)

       DOUBLE COMPLEX ALPHA
       DOUBLE COMPLEX X(*), Y(*), A(LDA,*)
       INTEGER M, N, INCX, INCY, LDA

       SUBROUTINE ZGERC_64(M, N, ALPHA, X, INCX, Y, INCY, A, LDA)

       DOUBLE COMPLEX ALPHA
       DOUBLE COMPLEX X(*), Y(*), A(LDA,*)
       INTEGER*8 M, N, INCX, INCY, LDA

   F95 INTERFACE
       SUBROUTINE GERC([M], [N], ALPHA, X, [INCX], Y, [INCY], A, [LDA])

       COMPLEX(8) :: ALPHA
       COMPLEX(8), DIMENSION(:) :: X, Y
       COMPLEX(8), DIMENSION(:,:) :: A
       INTEGER :: M, N, INCX, INCY, LDA

       SUBROUTINE GERC_64([M], [N], ALPHA, X, [INCX], Y, [INCY], A, [LDA])

       COMPLEX(8) :: ALPHA
       COMPLEX(8), DIMENSION(:) :: X, Y
       COMPLEX(8), DIMENSION(:,:) :: A
       INTEGER(8) :: M, N, INCX, INCY, LDA

   C INTERFACE
       #include <sunperf.h>

       void  zgerc(int	m,  int n, doublecomplex *alpha, doublecomplex *x, int
		 incx, doublecomplex *y, int incy, doublecomplex *a, int lda);

       void zgerc_64(long m, long n, doublecomplex *alpha,  doublecomplex  *x,
		 long  incx,  doublecomplex  *y,  long incy, doublecomplex *a,
		 long lda);

PURPOSE
       zgerc performs the rank 1 operation A := alpha*x*conjg( y' ) + A	 where
       alpha  is  a scalar, x is an m element vector, y is an n element vector
       and A is an m by n matrix.

ARGUMENTS
       M (input)
		 On entry, M specifies the number of rows of the matrix A.   M
		 >= 0.	Unchanged on exit.

       N (input)
		 On  entry, N specifies the number of columns of the matrix A.
		 N >= 0.  Unchanged on exit.

       ALPHA (input)
		 On entry, ALPHA specifies the	scalar	alpha.	 Unchanged  on
		 exit.

       X (input)
		 ( 1 + ( m - 1 )*abs( INCX ) ).	 Before entry, the incremented
		 array X must contain the m element 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 (input)
		 ( 1 + ( n - 1 )*abs( INCY ) ).	 Before entry, the incremented
		 array	Y  must	 contain the n element vector y.  Unchanged on
		 exit.

       INCY (input)
		 On entry, INCY specifies the increment for the elements of Y.
		 INCY must not be zero.	 Unchanged on exit.

       A (input/output)
		 Before	 entry,	 the  leading  m by n part of the array A must
		 contain the matrix of coefficients. On exit, A is overwritten
		 by the updated matrix.

       LDA (input)
		 On  entry, LDA specifies the first dimension of A as declared
		 in the calling (sub) program. LDA >= max( 1, m ).   Unchanged
		 on exit.
