a cell of double heading

Is it possible to add initial lines to a cell as if they were headings?

For example: given a cell of double 5x3 is it possible to add a line where the fields are strings?

Yes. Use Tables (link).

[Guido Pastore]

Can you post an example please?

[Star Strider]

Certainly.

I am not certain what you are starting with. That affects how the table (link) is created and addressed.

Try this:

C = {rand(5,3)};                                                        % ‘cell Of double 5x3’
C3 = mat2cell(C{:}, size(C{:},1), ones(1,size(C{:},2)));
T = cell2table(C3, 'VariableNames',{'Column_1','Column_2','Column_3'})

producing:

T =

  1×3 table

      Column_1        Column_2        Column_3  
    ____________    ____________    ____________

    [5×1 double]    [5×1 double]    [5×1 double]

To recover the data (in this illustration, others may be different):

    T1 = T.Column_1{:}

If you want to save it to a file, use the writetable (link) function.

If ‘C’ is a matrix rather than a cell array, the code changes a bit.

thank you

As always, my pleasure.

[Guido Pastore]

Sorry, I have another question.

I have, for example, 4 cell. How can I create a struct with all these cell??

[Star Strider]

I am not certain that I understand what you want.

If you want to assign the table to a structure element, try this:

S.T1 = T;

See the documetation on Structures (link) for details.
