When fitting the exponential function, I found that the fitting degree was better when the iterative algorithm selected Orthogonal Distance Regression (pro) in the fitting window (as shown in the figure). However, after consulting the X-Function help documentation, no instructions on how to select the iterative algorithm through script commands were found (the fitting functions in the nlbeginor and nlbegino commands can only be selected from implicit functions). At present, my script is:
nlbegin iy:=([Table]Data! 1, [Table]Data! 2) func:=ExpDecay2 nltree:=tr;
nlfit 100000;
nlend 1 0;
May I ask how I should select the iterative algorithm through script commands? |
