Can I convert empty strings to NaNs automatically in a cell array?

In MATLAB, I have a cell array containing nonempty strings, numbers, and empty strings. I want to change the empty strings to NaNs using a MATLAB function.

The CELLFUN command provides this functionality:

% Return a boolean array named 'empties' (with same dimensions as cell array

% 'A') with true for each empty element and false otherwise

empties = cellfun('isempty',A);

% Now change all the empty cells in A from empty strings '' to double NaN

A(empties) = {NaN};
