NAME
       BLAS/SRC/sger.f

SYNOPSIS
   Functions/Subroutines
       subroutine sger (m, n, alpha, x, incx, y, incy, a, lda)
           SGER

Function/Subroutine Documentation
   subroutine sger (integer m, integer n, real alpha, real, dimension(*) x,
       integer incx, real, dimension(*) y, integer incy, real,
       dimension(lda,*) a, integer lda)
       SGER

       Purpose:


            SGER   performs the rank 1 operation

               A := alpha*x*y**T + 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.

       Parameters
           M

                     M is INTEGER
                      On entry, M specifies the number of rows of the matrix A.
                      M must be at least zero.

           N

                     N is INTEGER
                      On entry, N specifies the number of columns of the matrix A.
                      N must be at least zero.

           ALPHA

                     ALPHA is REAL
                      On entry, ALPHA specifies the scalar alpha.

           X

                     X is REAL array, dimension at least
                      ( 1 + ( m - 1 )*abs( INCX ) ).
                      Before entry, the incremented array X must contain the m
                      element vector x.

           INCX

                     INCX is INTEGER
                      On entry, INCX specifies the increment for the elements of
                      X. INCX must not be zero.

           Y

                     Y is REAL array, dimension at least
                      ( 1 + ( n - 1 )*abs( INCY ) ).
                      Before entry, the incremented array Y must contain the n
                      element vector y.

           INCY

                     INCY is INTEGER
                      On entry, INCY specifies the increment for the elements of
                      Y. INCY must not be zero.

           A

                     A is REAL array, dimension ( LDA, N )
                      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

                     LDA is INTEGER
                      On entry, LDA specifies the first dimension of A as declared
                      in the calling (sub) program. LDA must be at least
                      max( 1, m ).
