Hi.
I had a nonlinear equation.so I solved it and I obtained set of points and plot them.for example (x,y) pairs are my results and plot(x,y) give me my diagram.
now,I want to use from fitting to obtain a relation between x,y.
I know general form of this relation is as following:
y = c1*log(x)+c2
how I can use from fitting to obtain c1 and c2 constants?
I saw in plot window of MATLAB there is not log function.and there is only polynomial functions for fitting.
how use from fitting in my problem?
thanks
