              Least squares, Orthogonal matrices.      
       
  a) Verify with numeric applications,

     * least squares solution of the linear system Ax = b.
     * properties of Orthogonal matrices.
 
  b) The coefficients, integers or fractions, are randomly
     selected by the computer.

  c) The size of the vectors, are randomly selected by the 
     computer, but you can selecte  the size  if you want.
   
      I have used gcc.2.9 (Dev-C++ 4), 
                  gcc.3.2 (v2DJGPP Rhide).
