Get the index of one cell of a cell array

Hi,

From a given cell of a cell array, how is it possible to easily and quickly get its index ?

Thanks for help.

Best.

Try reading the help for ind2sub or sub2ind

These functions are valid for cell arrays as well.

Ok thanks for your reply, but I forgot to mention this is for one dimension cell arrays in my case.

Suppose you have a cell array

A = {1,2,3,4,5};

and you extract a specific element of this array

a = A(4);

then, for a general case, you can find its index back using

idx = find(cellfun(@(x) isequal(x,a{:}), A))

if all the elements of A are scalar, then you can also write

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

Great, thank you for this very clear answer.

This is the kind of solution I was looking for.
