Dear Experts, I am trying to count , how many logical ones I have in my cell array.

I was trying these way's:

idx = find([mycell{:}] == 1);

idx=cellfun(@(c)any(c==1),mycell);

idx=cellfun(@(c)any(c>0),mycell);

These do not work.

Please, find a example cell array attached and share your opinions!

MAny thanks
