Same codes, same version matlab but different results on different computers

Greetings,

I am using MPT3.0 toolbox (https://www.mpt3.org/) to do my research related to multiparametric nonlinear programming. And MPT3.0 uses other libraries compiled in cpp.

When I used my laptop, I can obtain results as I expect. But I used my desktop at university, I may obtain errors sometimes and different results sometimes. The MPT3 toolbox version is same and other libraries are same version. Matlab version is same R2018a. I used fixed random seed.

What could be the reason? How can I detect which functions that cause the problem and make my results repeatable on both computers?

Thank you!
