29 Jan 2012 N-D histogram Extension to the histc function to count the number of data points on N-D grid. Author: Kota Yamaguchi

Hi Daniel,

You can use fixed step by manually creating range vector. For example,

edge = {[0,1,2,4,8,16], ...}

If what you need is a certain number of uniform edges in the observed data, you also might want to try linspace or logspace function.

edges = {linspace(min_val, max_val, 12), ...}

All the histnd does is to wrap histc function built in Matlab to allow multiple dimensions. If you need to get count of unique values, you need to use unique function instead:

[Xu, m, n] = unique(X, 'rows'); % this will find unique vectors Xu and corresponding index m.

h = histc(m, unique(m)); % histogram over unique index values

You should check the Matlab documentation of unique, hist, or histc function.

Thank you, Kota! I was about to write one myself too because I'm used to the join method in Ruby, but found yours. Nicely done!

Thanks, Yamaguchi! I like the idea of templates and the API - its a great add on for many types of projects; HTML generation, scripts etc. However my design would be different.

Very nicely done! I was about to write this myself, but this has saved me the effort. I like the way it handles arrays and cellstr arrays.

I'm curious: do you happen to be an IDL programmer? There is an IDL function of the same name with the "same" functionality.
