 Usage:  {wtsout, fout} = nnrdovm(param, wtsin)  
 
 Input:

  param                  3 x 1 vector number of weights, maximal number of iterations and 
                         tracing message visible 
                         
  wtsin                  vector input weights (either randomly generated or by 
                         the user generated). 
                         
 Output:

  wtsout                 vector output weights after optimization 
                         
  fout                   scalar minimal value of error function
