Add myaa.m to your path and enjoy anti-aliased professionally looking graphics in Matlab at any time. Myaa works with any kind of graphic (3-D, plots, scatterplots, ...) and even adds anti-aliasing to text, ui controls and grids. Myaa is ideal for complex, cluttered and saturated plots.
See attached screenshot for a demonstration. More examples included in the code, just run 'help myaa'.
For those of you who 'publish' your code often, an undocumented anti-aliasing option is included in the snapnow.m function in Matlab. To publish a file called test.m you can do:
opts.figureSnapMethod = 'antialiased';
However, you will have more control over the process using myaa, which is also the best choice when using Matlab interactively.
In any case: Anti-aliasing is good for you! :-)
