a=np.linspace(0,5,100)
b=np.linspace(0,6,100)
what is being plotted is 0-100 for a and b and not 0-5…

So I recently saw a post use linspace in Python, is this not a Matlab function? I cannot find it in the docs and was under the impression that the Python alternative for linspace is range. Is it part of some module/library/package?
