open cell array/structure

I have a .m file of cell array that I want to set in a uitable data, but the following error appears:

??? Error using ==> set Values within a cell array must be numeric, logical, or char

Then i repaired that the program open the file but in the format:

Data =

    {30x5 cell}

Not as a matrix.

Because the matrix has strings, and I want to set them in the uitable too, I can use the function cell2mat.

In fact, when I open the .m file it comes as a structure array, but I changed it to a cell array because i thought it would be better.. can someone help me?

As I said, the above error appears, I think that occurs because the matlab doesnt read the matrix, just a "{30x5 cell}". Whem my file only had numbers, i could use "cell2mat", then it becomes a matrix to matlab and the set worked well.

The error message is clear. "Values within a cell array must be numeric, logical, or char". use celldisp(Data) or open('Data') to check the value of Data. Does it contain values other than numerical, logical or char?

It contain:

'w' '5' '9' '0' '8'

'h' '7' '8' '9' '5'

before, it just had numbers, so i could use cell2mat. Now i cant set the data in the uitable:

before:

%saving

table_1 = get(handles.Tabela_Propriedades,'Data');

table = str2double(table_2);

uisave('table','dados');

%opening

[filename, path] = uigetfile('*.mat','Select the MATLAB code file');

Dados_1 = open([path filename]);

Dados = cell2mat(struct2cell(Dados_1));

set(handles.Tabela_Propriedades,'Data',Dados);

Now, I also have strings im my matrix, so i cant convert to double when I save, neither use cell2mat when opening.

You don't need to do any converstion. Just do:

%saving

table_1 = get(handles.Tabela_Propriedades,'Data');

uisave('table_1','dados');

%opening

[filename, path] = uigetfile('*.mat','Select the MATLAB code file');

Dados_1 = open([path filename]);

Dados = Dados_1.table_1;

set(handles.Tabela_Propriedades,'Data',Dados);

Guilherne, if that was what your cell Data contained, then MATLAB would not be telling you it is a 30 x 5 cell array.

Perhaps it instead contains

{'w'} {'5'} {'9'} {'0'} {'8'}

{'h'} {'7'} {'8'} {'9'} {'5'}

??

Thanks man! i didnt know i could use the data that way (Dados = Dados_1.table_1; ), problem solved, thank you again because of the patience with me and my terrible english!

[Guilherne]

Walter, that happened because my uitable size is 30x5, and it saves even the blank spaces, I think.
