Problem with matrices. Double and cell

Hello,

I have a problem with a matlab code. The problem is that I want to make o txt file with my results. I am using the command "writetable" nut there is a problem with matrixes. In the picture I show you the format of the matrices.

How can I convert cell to double In order to make this code?

P.S. I ve tried commands : cell2table,table2array, but it doesn't works...

Thank you

please attach your data as .mat file

For converting cell arras to double array, you could use cell2mat:

To answer this, we must see what is inside the cell array. Could you please share it?

Answer 1

[Andrei Bobrov]

for ii = 1:numel(CT)
    if ~iscell(CT{ii})
        CT{ii} = num2cell(CT{ii});
    end
end
T = cell2table(cat(2,CT{:}));
writetable(T,'youtxtfile.txt')

Answer 2

[Walter Roberson]

 Nc =  [CT(1), num2cell(CT{2}), CT(3), num2cell(CT{4}), num2cell(CT{5})];

 writecell(Nc, filename)

This requires r2019a or later, but we know that you have that because writematrix is introduced at the same time.

I used this command you suggested me, but unfortunately it doesn't works. The command wimndow wrote me these:

Error in test_v2_pro (line 85)

Nc = [CT(1), num2cell(CT{2}), CT(3), num2cell(CT{4}), num2cell(CT{5})];

Why ?

[Ivan Mich]

Also I've tried the command:

Nc = [CT(1,1), num2cell(CT{2,1}), CT(3,1), num2cell(CT{4,1}), num2cell(CT{5,1})];

writecell(Nc, 'filename.txt')

And it doesn't work too...

The command window showed me :

Error in test_v2_pro (line 85)

Nc = [CT(1,1), num2cell(CT{2,1}), CT(3,1), num2cell(CT{4,1}), num2cell(CT{5,1})];

ALSO , I ve tried these command :

Error in test_v2_pro (line 85)

Nc = [CT(1:1), num2cell(CT{2:1}), CT(3:1), num2cell(CT{4:1}), num2cell(CT{5:1})];

and it doesn't work too...

Do you have any idea why?

Thank you

[madhan ravi]

Could you attach your file as .mat ? , asking it for the second time.

[Ivan Mich]

I am sorry but i can't share this file..

[Walter Roberson]

We need the full error message showing what matlab thinks is wrong.

[Ivan Mich]

Error in test_v2_pro (line 85) Nc = [CT(1:1), num2cell(CT{2:1}), CT(3:1), num2cell(CT{4:1}), num2cell(CT{5:1})];

This is the full error message that command Window shows. This message is the same when I use the previous command I refer. Command Window does not shows me something else...

[Walter Roberson]

At the command line give the command

dbstop if error

and then run the code. When the problem occurs, try these and see which ones give an error and show us the error:

Nc =  [CT(1), num2cell(CT{2}), CT(3), num2cell(CT{4}), num2cell(CT{5})]
Nc =  [CT(1), num2cell(CT{2}), CT(3), num2cell(CT{4})]
Nc =  [CT(1), num2cell(CT{2}), CT(3)]
Nc =  [CT(1), num2cell(CT{2})]
Nc =  [CT(1)]

[Ivan Mich]

i gave the command you suggested me , dbstop if error, and command window show me this message :

Error in test_v2_pro (line 85) Nc = [CT(1:1), num2cell(CT{2:1}), CT(3:1), num2cell(CT{4:1}), num2cell(CT{5:1})];

The same message is shown when i am trying to use the commands:

Nc =  [CT(1), num2cell(CT{2}), CT(3), num2cell(CT{4}), num2cell(CT{5})]
Nc =  [CT(1), num2cell(CT{2}), CT(3), num2cell(CT{4})]
Nc =  [CT(1), num2cell(CT{2}), CT(3)]
Nc =  [CT(1), num2cell(CT{2})]
Nc =  [CT(1)]

Actually, I have to notice that my data are coming from .csv files. I don't know if this could help you to give some advice...

[Walter Roberson]

It is not possible to get that error from

Nc =  [CT(1)]

But in the meantime, please tell use more about CT{3} which your display indicates is a cell array.
