Epigram for the Histogram for Matlab/Octave (Episode #1) 

One Minute One-liners for the curious: https://www.youtube.com/@1minute1liners

In this YouTube short, I explain how to create a faster histogram function using arithmetic on indices. The one-liner in Matlab/Octave is:

Below are the functions inthist.m and the test code tinthist.m.
