Use of the IMSL Fortran Libraries at GMU
----------------------------------------

The IMSL Fortran Libraries are available on osf1.

The library is
    /usr/local/imsl_2.0/libimsl.a

Because the OSF compilier is f90 (instead of f77), to compile and link
a main program, say "foo.f", the statement is

   f90 -o foo.exe foo.f /usr/local/imsl_2.0/libimsl.a

Online help is available.  The command is 
   /usr/local/bin/imsl.idf

Here are a couple of examples:

To generate 5 Gaussian random numbers:

      integer iseed, nr
      real r(5)
      iseed = 123457
      call rnset (iseed)
      call rnnor(nr, r)
      print *, 'The random Gaussians are ', r
      end

To solve the linear system

 3x_1 +2x_2 + x_3  & = & 11
  x_1 +4x_2 - x_3  & = & 3 
  x_1 - x_2 + 2x_3 & = & 7


      integer n, lda, ipath
      real a(3,3), b(3), x(3)
      data a / 3.0,  1.0,  1.0,
     &         2.0,  4.0, -1.0,
     &         1.0, -1.0,  2.0/
      data b /11.0,  3.0,  7.0/
      n = 3
      lda = 3
      ipath = 1
      call lslrg (n, a, lda, b, ipath, x)
      print *, 'The solution is ', x
      end
