Hello everyone,
I am trying to calculate velocity and acceleration of a length change out of the 'AddDist' matrix. I am thinking of using V=(length 2 - length 1)/time for velocity (which should give me a vector not scalar?) and a=(V2 - V1)/time for acceleration. But I am not sure how to make MatLab have the 2nd column subtracts the 1st column, then the 3rd column subtract the 2nd column, and so on...
this is what I thought how it would work but it didn't seem to make sense in MatLab for calculating what I want. 0.002 is my time as the time gap between each rows is always 0.002s.
end
I am still trying to learn coding in MATLAB. Sorry if my question is too basic. Thank you for your help and time in advance!

Use the diff function.
