Harmonic ratio from acceleration

Hi everybody, I am pretty new user of matlab and I have one work with it I have an accelerometer to analyse the walk: from acceleration in XYZ-axes I have to calculate some parameters. In particular harmonic ratio (that describe the gait smoothness). I just know I have to start appling Fourier Trasform and later find all valleys and peaks that will represent the "even" and "odd" amplitudes Harmonic Ration is Even/Odd. Anybody can help me with code for matlab for this work? Thank you :)

Hi, did you ever find out how? Looking for sample code and would be very appreciated for my project.

Hi, have you ever found out how to do the calculations? I'm also searching for a matlab solution...
