Hello all, I am having a 4 dimension .mat file. I want to access the contents of this file.
My query is that when I double click it then it displays the following message: " Preview too large to be displayed properly."
Any help in this regard will be highly appreciated.

Thank u so much sir for ur prompt reply... I tried saving this file (somefile.mat x y z). On saving, this file appears in current folder and when I double click this file then in coomand window following message is seen: load('somefile.mat').
But still I am not able to view contents inside this file i.e., somefile.mat x y z

once maltab loads the data (after you double clicked on the mat file in the folder window) , the variables shoud appear in your workspace window :
you can also type whos in the command window , and you should see :

Hi chaaru,
I understand that you're encountering the message 'Preview is too large to be displayed'.
When you double-click on the matfile, the contents of the file are loaded into the workspace.
If you want to view a particular variable, you can double-click on it in the workspace. If the size of the clicked variable is very large, the message 'Preview is too large to be displayed' will appear.
You can access the contents of the variable through indexing. For example, to access a specific slice or subset of the 4D array, you can use:
slice = myData(:, :, :, 1); % Access the first 'page' of the 4D array
Refer the documentation below for better understanding:
Hope it helps!
