I saved a 60x300,000 matrix from MATLAB online into my MATLAB drive. But when I load the mat file from my local workstation, the entries in the matrix are not the same as the original ones. The values is exact for only one digit.

when you load the mat file in matlab online, are the values still 'correct'?
which format are the numbers? double?
also note that the first column is identical. Maybe you loaded the wrong file / did not refresh the data when runnning your code mutipe times?

Yes. The numbers' format is double. When I load the mat file in matlab online, the values are still correct. But there is a limit of memory in matlab online, so I need to load the mat file into my pc.

It worked now. I cleared all variables in my pc's matlab and reloaded again.

great.
sounds like you ran a script. Use functions instead, this way the variables are cleared each time before you run
