Same code but different results

I run the same code on both matlab online version and PC version(2021b), but get different output. The PC version works good in every iteration but the online version output "Nan" just after few iterations. Does anyone have any idea why this is happening?

MATLAB Online is one release newer (R2022a)

MATLAB Online is Linux based, and uses different high-performance Math libraries than PC uses.

It might be the case that you are using matrices that are badly conditioned, but which might be permitted through in your PC but rejected in MATLAB Online.
