How to read .mat file data

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.

You are confusing concepts that apply to variables with concepts that apply to .mat files. Variables like x=rand(4,4,3,2) are 4-dimesional. However .mat files are files and do not have dimensions.

Perhaps you consider a .mat file to be 4D when it contains a 4D variable. That wouldn't make too much sense, because a .mat file will generally contain multiple variables of different dimensions, e.g.,

x=rand(4,4,3,2);
y=rand(5,7);
z=rand(5,5,5,3,8);

save somefile.mat x y z

My query is that when I double click it then it displays the following message

Shouldn't happen. Double-clicking a.mat file in the Current Folder window should load it into the workspace. Perhaps you meant single-click. Or, perhaps you are clicking on a file in an environment other than the Matlab Desktop.

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

@chaaru datta

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 :
