Data saving, data import cell

I have a saved cell 12x12x12 in a file, which I want to recall into another file for some calculation.

How can I read the matrixes of the cell i have in the new file?

hello

you can save and then load the cell in its original format , like here (created A , saved it and reloaded it afetr clearing my workspace)

A = rand(3,3,3)

A(:,:,1) =

    0.8147    0.9134    0.2785
    0.9058    0.6324    0.5469
    0.1270    0.0975    0.9575


A(:,:,2) =

    0.9649    0.9572    0.1419
    0.1576    0.4854    0.4218
    0.9706    0.8003    0.9157


A(:,:,3) =

    0.7922    0.0357    0.6787
    0.9595    0.8491    0.7577
    0.6557    0.9340    0.7431

>> save AA.mat A
>> clearvars
>> load AA.mat
>> A

A(:,:,1) =

    0.8147    0.9134    0.2785

    0.9706    0.8003    0.9157


A(:,:,3) =

    0.7922    0.0357    0.6787
    0.9595    0.8491    0.7577
