Even though widely used, #matlab and #octave 's jet colormap is not a good choice for visualizations due to poor grayscale conversion, as explained here: http://cresspahl.blogspot.de/2012/03/expanded-control-of-octaves-colormap.html . I suppose its visual appeal lies in the colorfulness, hence many replacements probably lack the multicolored gradient. The “antijet” colormap is based on the (reverse) visual spectrum, ranging […]

GNU Octave's more beautiful Matlab syntax #octave has build up quite a number of improved syntax features compared to mathworks #matlab. Let me list a few that I find noteworthy: Octave has default arguments for functions: function r = func(a=1,b=2) Octave has assignment operators, like: += , -= , *= Octave has the very handy […]
