Place zero in an empty matrix within cell array?

I have a cell array (x) where in this case there is no value in one of the cell matrix. I want to add a -1 value in the matrix as a way of 'place-holding' that column. I've tried these approaches:

emptyCells = cellfun('isempty',x);
x(emptyCells) = -1;

x(isnan([x{:}]))={-1}

x(cellfun(@isnan,x))={-1}

Any help would be greatly appreciated.

x(emptyCells) = {-1};

Ahhhh so simple, so effective. Thanks a lot!

Basically, since x is a cell array, any subset of it using parentheses like x(whatever) is also a cell array, which means the right hand side needs to be a cell array also for the assignment to work like you want.
