How to create a nested cell file?

Hi,

I want to have a cell file with 5 structs. In each struct, I should have two folder (A,B). Then, in each of these A and B, I want to have some folders up to 30 number. In each of these folders I should have a cell 12*31. Can I write it as below?

DATA{5}.A.B.C{12,31)=My data

I assume you mean "fields" or "members" rather than folders (like operating system folders where files live).

Why do you want a cell array, with each of the 5 cells containing a single structure? It makes more sense to have a structure array.

Please review the FAQ on cell arrays.

For example, from the documentation:

field1 = 'f1';  value1 = zeros(1,10);
field2 = 'f2';  value2 = {'a', 'b'};
field3 = 'f3';  value3 = {pi, pi.^2};
field4 = 'f4';  value4 = {'fourth'};

s = struct(field1,value1,field2,value2,field3,value3,field4,value4)

s = 1×2 struct array with fields:
    f1
    f2
    f3
    f4

s is a 1x2 structure array because value2 and value3 have 2 values.

DATA(5).A.B.C=rand(12,31);
DATA(1)

ans = struct with fields:
    A: []

DATA(5)

ans = struct with fields:
    A: [1×1 struct]
