My script behaves differently when I run it from Linux platform

I have a script that reads a csv file and generates a couple of text files. It basically uses readcell function several times, perform some calculations and writes a couple of text files.

I run the same script on the same csv from a Windows launched Matlab 2019 and do the same thing from a linux launched Matlab 2020. My generated text files do not match. I do not have the same versions installation at my disposal unfortunately.

Is there something simple and obvious I should change in my m file?

Please mention, what the difference between the files is. "Do not match" can mean a lot of different things. Maybe just the line breaks?

My script works as expected when I run it in Windows. The differences are not just line breaks. For instance, below is a part of the differences:

linux: 76.2 = Front Leaf Length (mm); vs Windows: 842 = Front Leaf Length (mm)

linux: 200000 = Rear Leaf Length (mm) vs Windows: 842 = Rear Leaf Length (mm)

linux: 79000 = No. of Elements per Front Leaf (<= 45) vs Windows: 30 = No. of Elements per Front Leaf (<= 45)

@Javid Moraveji Can you upload the script and the csv file?

[Javid Moraveji]

Unfortunately, I am not allowed to share the files.

It is not possible to guess, why your code creates a 76.2 under linux and 842 under Windows. Either you process different data or there is a problem with the interpretation of text or binary files. Without seeing the input values and the code, there is no chance to find the reasons of the differences.

Or perhaps there are steps involving near-singular matrices.

Thanks everyone!

@Jan: I tried my script on the same csv file. You are right about the processing different data sets; however, this is due to the way reacell handles the csv files when there are blank rows in R2020 vs R2019.

I am told that the readcell function (which seems to be fairly new) behavior has changed in R2020; so, nothing to do with the OS.
