Hi,
I have a row vector containing 120 data points. How would I convert that data in to 100. I am working on gait cycles and would like to analyse the knee angles at a certain percentage of the cycle. This is what I was attempting to use but that just seems to ignore any data points past the 100th value.
y = linspace(1,100,100); Gait_Cycle_Percent =interp1(x,y) where x is the raw 120x1 data.
Thank you

If you have the signal processing toolbox:

Yes i would love to see what parameters you ended up using for this.

newdata = resample(originaldata,100,length(originaldata));
