I have a 7x1 cell array called X.

exist(X) does not work as I am not allowed to apply it on type cell.
Is there any solution for this problem, please?

Thank you.

Hi Blue, you have to include the name of the variable, be it a cell array or not, in single quotes.

A = cell(2,1);
exist('A')

Hope that helps,

To which I would add that unless you have specific reason not to, you should use

exist('A','var')

just in case your variable name happens to be the same as the name of a
function or the like.
