SimplexOld:

--------------------------------------------------------------------------
   Uses the simplex method to minimize the cost when solving the problem
   au = b and the cost is cu.
--------------------------------------------------------------------------
   Form:
   x = Simplex( c, a, b )
--------------------------------------------------------------------------

   ------
   Inputs
   ------
   c             (1,n)    Cost vector

   b             (3,1)    Right-hand-side

   -------
   Outputs
   -------
   x             (n,1)    Solution
