cgeru(3P)		    Sun Performance Library		     cgeru(3P)

NAME
       cgeru - perform the rank 1 operation   A := alpha*x*y' + A

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

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

       SUBROUTINE CGERU_64(M, N, ALPHA, X, INCX, Y, INCY, A, LDA)

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

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

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

       SUBROUTINE GER_64([M], [N], ALPHA, X, [INCX], Y, [INCY], A, [LDA])

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

   C INTERFACE
       #include <sunperf.h>

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

       void cgeru_64(long m, long n, complex *alpha, complex  *x,  long	 incx,
		 complex *y, long incy, complex *a, long lda);

PURPOSE
       cgeru  performs the rank 1 operation A := alpha*x*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.
