I wrote a piece of labtalk code following the example of another member i.e. by "easwar" , but I keep on running into the same mistake: the extremes of the data interval to fit never change. This is crucial as I am trying to fit the whole data range in sequential steps. Can, please, somebody explain to me where I got it wrong? Thank you very much once again in advance... This is just a test code, but still not working: // Get length of active dataset limit %c; // Number of groups numgroup = 10; // Initialize NLSf object nlsf.init(); // Assign function nlsf.func$="FermiLiquid"; // Point to active dataset nlsf.fitdata$=%c; // Loop over each group of points in active dataset for(i = 1; i <= 2; i++) { // Use mks1, mks2 to set data markers mks1 = 2 + (i-1)*10 ; mks2 = 12 + (i-1)*10 ; // Give some initial value to parameters nlsf.p1=0.00037; nlsf.p2=0.00000114; nlsf.p3=1.4; // Iterate nlsf.iterate(5); // Report to script window; type $numgroup; type $(mks1); type $(mks2); type Data Fitted from $(mks1) to $(mks2); type Param1: $(nlsf.p1) +/- $(nlsf.e1); type Param2: $(nlsf.p2) +/- $(nlsf.e2); type Param3: $(nlsf.p3) +/- $(nlsf.e3); type Reduced ChiSqr: $(nlsf.chisqr); type ""; } [/quote]   Check here to include your profile signature.
