Making MATLAB pretty

Alright all y’all haters, it’s MATLAB time.

For better or worse, MATLAB is the language that is used for scientific programming in neuroscience. But it, uh, has some issues when it comes to visualization. One major issue is the clusterfuck that is exporting graphics to vector files like eps. We have all exported a nice-looking image in MATLAB into a vectorized format that not only mangles the image but also ends up somehow needing thousands of layers, right?  Thankfully, Vy Vo pointed me to a package on github that is able to clean up these exported files.

Here is my favorite example (before, after):

If you zoom in or click the image, you can see the awful crosshatching in the before image. Even better, it goes from 11,775 layers before to just 76 after.

On top of this, gramm is a toolbox to add ggplot2-like visualization capabilities to MATLAB:

(Although personally, I like the new MATLAB default color-scheme – but these plotting functions are light-years better than the standard package.)

Update: Ben de Bivort shared his lab’s in-house preferred colormaps. I love ’em.

Update x2: Here’s another way to export your figures into eps nicely. Also, nice perceptually uniform color maps.
