Curve Fitting

Hello All,

I have two data sets, one obtained from experiments and the other i got from matlab simulation. I would like to fit the simulated data with experimental data (the simulated data is obtained from a linear equation depending on concentartion). Can anybody tell me what's the best way to do that in Matlab? I tried to do that using excel solver but i am not satisfied with it.

Hope to get some good advice soon.

Regards!
