Troubleshooting Matlab: Issues with Saving and Loading FNET Variable

[Old Guy]

I have calculated a variable called FNET. I have saved FNET to the hard drive using the following command:

save(fullfile(BasePath,'FNET'),'FNET','-mat')

BasePath is a string that gets the file to the correct directory on my hard drive.

First Question: FNET shows up in the correct place, but in Windows Explorer the file type is shown as "File" rather than (what I would expect) MATLAB M-file. Why?

Second Question: I've written a program that needs to load this variable. None of the following commands have worked:
load FNET
load fullfile(BasePath,'FNET.mat')
and various other attempts.

Please help!

I may have figured this out, which raised another question that I hope someone can answer for me. I had saved the variable in a file with the same name as the variable. However, I realized later that the file name was not exactly the same as the variable name, so I changed the file name. Apparently, this did not change the variable name. Is it correct that if you save a variable in a file, and change the file name, the variable name remains unchanged? This seems logical, but I would appreciate verification that Matlab actually works that way. Thanks.

I understand the importance of troubleshooting and resolving technical issues in order to ensure accurate and reliable data analysis. In regards to your first question, the file type displayed in Windows Explorer is determined by the file extension, not the contents of the file. In this case, the "File" type is most likely due to the fact that you used the "-mat" flag in your save command, which indicates that the file is in the MATLAB format. This is the expected behavior and does not affect the functionality of the file.

Moving on to your second question, there could be several reasons why the load command is not working for you. One possibility is that the file path is not correctly specified. It is important to double check that the BasePath string is pointing to the correct directory where FNET is saved. Additionally, make sure to include the file extension in the load command, as in "load(fullfile(BasePath,'FNET.mat'))". Another potential issue could be that the file was not saved properly and is corrupted. I would suggest trying to open the file in MATLAB and see if it loads successfully. If not, you may need to re-save the variable or check for any errors in the save command.

If these troubleshooting steps do not resolve the issue, it may be helpful to provide more information about your program and the specific error messages you are receiving. This will allow for a more targeted and effective solution. In general, it is always a good idea to carefully check your code and error messages, as well as to consult any available documentation or online resources related to the issue at hand. I hope this helps and good luck with your analysis.
