Error loading .mat

When I tried to load a .mat file, there was an error: cannot read file. The data is from exported from simulink using "to Workspace" block.

I have tried adding the folder into the path, but the error is still there.

>> load('Data.mat')

Error using load

Cannot read file C:\Users\Desktop\Work\Varying\Type1\Data.mat.

addpath(genpath(('C:\Users\Desktop\Work\Varying\Type1\')));
load('Data.mat');

The problem is not in locating the file so addpath is not going to help here.

The file was found in the indicated location but the user did not have permission to read it, or it is locked.

Possibly the file is empty, but I seem to recall that you get a different message for that.

You would get a different message if the file exists and is readable but is not valid.

Is it possible that Simulink still has the model running? The file might be locked if so.

I have stopped the Simulink model. The file was saved yesterday and I am trying to open it today. However was met with that error.

I tried using the code but it does not work too.

I ran the model to get the data again and saved the workspace. When I restarted my computer this time there was no error however there was no data loaded too.

Could you replicate this behavior? I would also like to know the size of this mat-file.
