I need to import this file in matlab, make a few changes and then export it again as .mhm. Before doing anything, I wanted to be sure that I can indeed save the file with this format but I'm having problems doing so. First, I have loaded it as a Table just using the GUI for now.

Then I tried saving with

save('Final.mhm', 'Final')

The file gets saved but when I try to open it, it only opens a series of seemingly gibberish characters. Then I tried:

writetable(Final, 'ProvaFinal.txt')

This works. I can save as .txt and then manually change the extension to .mhm

However, I would like to do everything programmatically in Matlab (also I have to do this for hundreds of files).

I tried:

writetable(Final, 'ProvaFinal.mhm')

As expected, it didn't work. Can I save a Matlab file as a .mhm?

Here is a copy of the file https://drive.google.com/file/d/1RcS_S3dJVBdrXEc6ibB9KTcm1eU4W-xt/view?usp=sharing

Answer 1

File extensions aren't really important. In this case, however, the .txt extension implicitly tells Matlab that you want to write a space-delimited file.

From the documentation:

writetable(T,filename) writes to a file with the name and extension specified by filename.
writetable determines the file format based on the specified extension. The extension must be one of the following:

• .txt, .dat, or .csv for delimited text files
• .xls, .xlsm, or .xlsx for Excel® spreadsheet files
• .xlsb for Excel spreadsheet files supported on systems with Excel for Windows®

So you should be able to write it to a .txt file and then rename the file from within MATLAB.

writetable(Final, 'ProvaFinal.txt');
movefile('ProvaFinal.txt', 'ProvaFinal.mhm');
