- I am writing a program in tp in order to do calculations of my experiment.
- Using a cursor I mark on the plot the points on which I want to carry
- out the curve fit to the equation Y:=a + b*exp(-c*x);
- I am using the marquardt levenberg algorithm to do so. My program works
- satisfactorily for all sets of data except for one set. I tried to fit
- this data in sigma plot and could do it but I am interested in knowing
- what could be the problem. Its a trivial thing but baffles me.
- You can repply to me personally.
- Thanks in advance
- Rxk.
