I updated my system to 10.10 Yosemite. I knew there were problems with MATLAB, but I saw that a patch was apparently already submitted by MathWorks.
So I upgraded, tried to open MATLAB, but it would tell me that it's not working with my version of OS X. The workaround for this was simple, but then it showed some errors with Java (the usual ones, there are many other people reporting that very same problem with other versions of MATLAB)
I downloaded the patch MathWorks provided for this specific problem and tried to run it, but it would tell me that it couldn't find an appropriate version of MATLAB. So apparently, MathWorks managed to patch the "standard" version of MATLAB 2013a, but not the student version. I mean, sure, I paid less for it, but I paid for it nonetheless and am kind of angry that MathWorks dropped support for a version of MATLAB that I bought just a year ago. I also don't see the technical issue here, as the student version is basically identical to the standard version to my understanding. So maybe someone knows a workaround for the "lesser people" out there.
