First off, congratulations to William for raising the money for a copy of MATLAB 2014. I look forward to PIVlab 1.4!
Here's my question: as part of my PhD studies a colleague of mine has created some MATLAB code that automates some of the analysis I've been doing with PIVlab/MATLAB. He's OK with me including the code with my thesis, and releasing it under a Free software license. Which licenses are acceptable for MATLAB code? As PIVlab is under a BSD license, does this code also need to be a BSD release?
that's something I don't really know... Please have a look at the included license text in the Pivlab archive. Please also look at the figshare website for Pivlab, there might be more information on licensing.
