Check if cell contains another cell

Hey,
I need to check if my cell contains another cell or if the contant is a character vector.
So I got a
a=1x130 cell
and
a{1}='1-v1';
a{2}='.*'
a{3}='3+v2'
a{4}=1x3 cell
...
So e need to check wether the cell content is a character vector like a{1} or a{3}, contains an operater such as a{2}, or a cell itsself with the same structure as a
Then I wanna
eval('(1-v1).*(3+v2)')
So with
ischar
I can check wether its .* or an character arry, but how do I check if its a subcell, to call the fiunction recursive?
Best regards

a{1}='1-v1';
a{2}='.*';
a{3}='3+v2';
a{4}={'this is a cell'};
cellfun(@iscell,a)

The image really isn't enough. I can't run the following code -- which exposes the fact the first cell really does contain another cell -- on your image.
load(websave("segs","https://www.mathworks.com/matlabcentral/answers/uploaded_files/1163423/testdata.mat"),"segs");
segs(1)
segs{1}
segs{1}{1}
segs(2)
segs{2}
I think you were getting fooled by the fact that the Variable Editor interface seems to look inside 1x1 cells.

Hi,
you can use the isa function:
isa(a{i},'cell')
Note that the use of eval is not recommended for many a good reason...

I believe you have got your answer already, as the cyclist pointed out the fact that variable viewer is not a reliable way to check the class of data, rather a viewer that helps you to analyze data. And we can trust the isa/iscell commands, which is not really surprising, considering how long they have been a part of MATLAB...
