I have the following Excel file which contain my data.
The input data is the number of cycles (N) while the output data is the capacity at different temepratures (278.15, 298.15,308.15, 318.15 ).
I want to fit the input and output data with a single function or mathmatical formula, preferably the following equation:
Therfore, what I want to do is to get C that correspond to (T and N) everytime. a1-a5 are free fitting parameters.
For T is is clear that I want it to chage only from 278.15 to 318.15.
Can I solve this using lsqcurvefit? or any other better appraoch?
