I am a beginner with numpy, and I am trying to extract some data from a long numpy array. What I need to do is start from a defined position in my array, and then subsample every nth data point from that position, until the end of my array.
basically if I had
a = [1,2,3,4,1,2,3,4,1,2,3,4....]
I want to subsample this to start at
a and then sample every fourth point from there, to produce something like
b = [2,2,2.....]
