Curve Fitting, Periodic Function

Hi friend.
I was doing gait analysis and I got a cycle of joint angle data. Then I used cftool to fit the curve,
but the function fitted out just matched with data in one cycle, after one cycle, the curve does not go as the second cycle. But It should be periodic within all time.
How could I get the right function which is cyclic with a period of gait?
Thank you very much

You might be interested in my free knot spline tool that can handle periodic function.
