Fit exponential curve through data points in Matlab

Question

Having data of an exponential decay available, I would like to fit a curve through it. How can I do that in Matlab?

Answer 1

Try this:

ft=fittype('exp1');
cf=fit(time,data,ft)

This is when time and data are your data vectors; time is the independent variable and data is the dependent variable.

This will give you the coefficients of the exponential decay curve.

Answer 2

If by fit you mean least squares, you should try lsqcurvefit
