How do I run the "UComp" library as a MEX file without causing MATLAB to crash?

I am trying to use "UComp", a C++ library for statistical modelling, within MATLAB 2022a by compiling it as a MEX file.  More info about "UComp" can be found here:

https://github.com/djpedregal/UComp

The MEX file builds successfully, but MATLAB crashes whenever I call the MEX file.

How do I use the "UComp" library without crashing MATLAB?

The MEX file for the "UComp" is not intended to be run directly in MATLAB, and doing so will likely create a segmentation violation and cause the whole MATLAB process to crash.

In this case, you should use the wrappers provided by the "UComp" library. Instead of calling the "UComp" function (which calls the MEX file directly), you should add the folder containing the "UComp" function's MATLAB wrapper (likely called something like "UCompMATLAB2.2.2/") to the MATLAB path. You can then call the "UC" function in MATLAB using the "UC.m" file instead.
