In this repo I would like to share some Matlab code to solve quadratic constraint optimization problems with quadratic cost. I find it quite interesting, that there are so few free solvers in Matlab code out there for this type of problem, even though it occurs quite frequently. I'm not an expert in Matlab syntax, so if anyone wants to participate in making this thing more convenient feel free to contact me. If you want to use the code for your project please go for it.
