how use from fitting for log function?

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
