URL: <http://savannah.gnu.org/bugs/?36473> Summary: colormaps different from matlab Project: GNU Octave Submitted by: carandraug Submitted on: Tue 15 May 2012 11:12:53 AM GMT Category: None Severity: 3 - Normal Priority: 5 - Normal Item Group: Matlab Compatibility Status: None Assigned to: None Originator Name: Originator Email: Open/Closed: Open Discussion Lock: Any Release: dev Operating System: Any _______________________________________________________ Details: Hi I noticed that the colormaps we have in Octave are a bit different from matlab. I have noticed this when trying to implement imhist and kept getting different results from matlab, then I noticed that after indexing my images were different. For example: jet(1) [0 1 1] # matlab [0 0 0.5] # octave m = jet; jet(1:3, :) # in matlab 0 0 0.5625 0 0 0.6250 0 0 0.6875 # in octave 0.00000 0.00000 0.50000 0.00000 0.00000 0.56349 0.00000 0.00000 0.62698 I didn't try every single colormap as I don't have matlab and didn't want to bother anyone too much but at least jet and hot are different. Is this considered a bug? Should I even try to fix it?
