convert cell to integer

I have a 1*1 cell in which its content is ineger. I need to convert the content to integer (no cell anymore just like a number itself)

how can I do that?

I tied cell2mat but did not work. It is like this now:

kar =

1×1 cell array

{[3]}

"I tried cell2mat but it did not work"

What does that mean? Did you get an error? If so, what was the full error message? If your example accurately describes your data, it should work.

kar = {[3]};
cell2mat(kar)
% ans =
%     3

whos kar % Paste the results from command window here

While you're at it, let us know what this returns or if it returns an error, too.

class(kar{:})
size(kar{:})

If ‘kar’ is initially:

kar = {{[3]}};

try this:

n = cell2mat(kar{:})

producing:

n =
     3

I get this error:

>> cell2mat(kar{:})

Brace indexing is not supported for variables of this type.

Error in cell2mat (line 36)

if isnumeric(c{1}) || ischar(c{1}) || islogical(c{1}) || isstruct(c{1})

Initially kar is :

kar =

1×1 cell array

{[3]}
