"Suggest a code"...
Well, anyway, let us know if you have the Curve Fitting Tbx or Optimization Tbx available (output of 'ver' command) and provide a sample of data like 20 data points and then we can suggest an approach for you to code.

Sorry, should read
[x,resnorm] = lsqcurvefit(myfun,x0,xdata,ydata);
Best wishes
Torsten.

@ Torsten The below messsage is displayed on the command window
lsqcurvefit stopped because the final change in the sum of squares relative to its initial value is less than the default value of the function tolerance
