Purpose:      
              Fit an approximating function to a table column.
              The function is defined with the command EDIT/FIT.
              See SET/FIT for modifying the method, weighting or printing
              options.

Syntax:       
              FIT/TABLE [nfeval[,prec[,metpar]]] table dep,[wgt] ind [funct]
\ys\pa
              nfeval   = maximum no. of function evaluations to be performed.
                         If nfeval positive then initial values of the
                                      parameters are the user guesses
                            nfeval negative then initial values are taken from
                                      the previously computed paramter values
\ap\pa
              prec     = precision to be achieved.
\ap\pa
              metpar   = method parameters (different from one method
                         to another, see manual for more details)
\ap\pa
              table    = table with the input data
\ap\pa
              dep      = reference to the column with the dependent variable
\ap\pa
              wgt      = optional reference to the column with the weight or
                         deviation of the measurements (see SET/FIT WEIGHT=)
\ap\pa
              ind      = reference to the column(s) with the independent
                         variable(s)
\ap\pa
              funct    = is the approximating function name. By default
                         the last used function is taken.

Examples:
\ex
              FIT/TABLE 10,0.0005,0.2 TABLE :Y :X1,:X2 TEST
              perform 10 function evaluation in the fit, with a relaxation
              factor 0.2 (if default have not been modified by SET/FIT i.e.
              METHOD = NEWTON), to reach a precision of 0.0005. Initial
              values of the parameters are the user guesses defined in the
              function TEST.
\xe\ex
              FIT/TABLE -10,0.0005,0.5 TABLE :Y :X1,:X2
              perform 10 function evaluations in the fit, using as initial
              parameters the values computed by the previous command.
