I tried to generate such kind of data file with the following Matlab script:
c1=fillcell();
c2=fillcell();
c3=fillcell();
save("c.mat","-v7.3","c1","c2","c3")
function c = fillcell()
c={};
for j=1:11
c{j}=rand(711,711,33);
end
end
The c.mat file is 4.18GB and I managed to load it in Scilab.
How much physical memory do you have on your machine ?

Hello,
I tried but failed to generate similar data.
What I had was a mat file containing mainly 3 cells.
Each Cell contains 11 hypermatrices that are 711x711x31 or 711x711x33.
I won't have access to the machine that can play with this data in the
coming days, so I am not sure I can help in the short term.

Hello Antoine,
I made a 4Gb file with Matlab:
>> a=rand(645,645,645);
>> b=rand(645,645,645);
>> c={a,b};
>> save("c.mat","-7.3","c")
and managed to load it successfully in Scilab:
--> loadmatfile("c.mat");
--> c
c =
[645x645x645 constant] [645x645x645 constant]
Maybe the structure I tried is too simple (just two hypermatrices in
a cell) so please give us a representative failing example.

Hello All,
I cannot open large matfile in scilab (~3.4Gb).
Scilab is always dying with an error message that is extremely
instructive: "Killed".
It's a bit cumbersome to share this big fie, so do you have any idea
on how to investigate this issue and try to locate the root cause?
As a side note, it might be a problem related to either the size of
the variables or their nature: cells containing hypermatrices.
The file itself is not corrupted (I managed to open it in matlab and
to save each hypermatrix into individual files that got imported in
scilab with no problem.
Cheers,
Antoine
