Two identical .mat files produce different resultss

DDD (2).zip (154.8 KB)
The file “ss” was created by someone else, while “ss1” was created by me. However, it is strange that when comparing the two data using MATLAB, it reports differences even though the data is supposed to be identical. “ss.mat” can run normally, but “ss1” cannot. What could be the reason for this?


The different message is due to tiny numerical differences. But even the “working” version has a singularity issue.
