Relative a movement - biomechanics

Hello guys, Thus, I have capture a movement of a person throwing a ball, however the amount of frames they have are different. I wonder, how can I make them to be expressed as percentages of the movement, so all participants get from 0% (beginning of motion) and end in 100% (last scanned picture)? Therefore, people have the same number of frames.

Sounds like you will want something from the interpx family:

doc interp3 %and friends

Let me see if I understand! I will create an array with the data I have and with another count of elements that I have, for example, matrix I want to interpolate a = [2 6 8 9 10] and other data with b = 1:1:5 and after that I created another array with the size I want to interpolate c = 1:1:100 and use the command interp1 (b, a, c, 'spline'). Am I Correct?
