Drag and Lift coefficient from Least square regression
 

Hello,

I have a lift and drag load (Newton/meter) function of time and the velcoity field function of time. Both are sinusoidal.

I would like to know how can I compute the Drag and Lift coefficient from a Least Square Regression or Fourier Transform.

Can someone point to a document showing how to do such thing in excel or mathlab ?

Thanks much

For a least square polynomial interpolation try :

polyfit

in Matlab.
