In order to make a logical array of it, you'll have to specify the conditions where the output is true. Consider two examples:
A = {1; 1; 1; []; 1; 1; []; 0; 0.1}
% true if non-empty
B = ~cellfun(@isempty,A)
% true if nonzero
C = cellfun(@(x) x~=0,A,'uniform',false)
% true if non-empty and nonzero
D = cellfun(@(x) ~isempty(x) && x~=0,A)
Note that the second example is still a cell array. This is required if empty elements are to be preserved,.

When the elements of the cell array are numerical arrays, this is faster:
B = ~cellfun('isempty', A)
