I extracted some data for a work using MATLAB and plot these values, but because the number of values in the array were many, my model had lots of noise in it. So i would to know how I could select just a few points which are spread along the plot from the start through to the end.

k=round(numel(Data)/100);
Data(sort(randperm(end,k))
This will give you a random sample of your vector.
