29 May 2013 histoutline Plot a histogram outline Author: Matthew Foster John

This is nice. I have two suggestions:

1. Counts generated from "hist" are centered on x, but "stairs" treat each x as where the steps occur, resulting in a half-a-bin shift between the outline and the actual histogram. Please consider correcting for this shift.

2. Sometimes the outline can end "mid-air" on either ends due to non-zero counts. Patching both ends with an extra bin of zero should fix this.

AND, as I'm typing this I just noticed that's exactly what rafi pl suggested with his codes.

This histogram plotting tool is very useful. By any chance, have you also worked on spherical secplot?

24 Jul 2011 plot_colorbar Plot a colorbar as a figure for publication. Author: Matthew Foster Matthew

I was able to get my desired result (scale from [0 8]) by changing one the lines to set(gca, 'yticklabel', [0, ticks/10]); and then running the program with the limit 80.

23 Jun 2011 Diffusion Distance Calculate the diffusion distance between histograms Author: Matthew Foster WurmD

the check "all(size(dist) >= size(kernel))"
prevents the comparison of vectors.

To be able to compare vectors with this distance, i've changed it to:
"~isscalar(dist)"

19 Nov 2010 plot_colorbar Plot a colorbar as a figure for publication. Author: Matthew Foster Pospiech, Matthias

does not work for me: It requires an axis handle
map = colormap(axishandle, cmap(dims(1)));

and since it can not be used as an exact replacement of the orignal colormap I can not use without rewriting most of my and of this plugins code
