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 ).
