I have a 3D cell RowXColXDep (12X125X1216), I want to find the empty cells (which row, column, and depth). I used:
[Row Col Dep] = find(cellfun(@isempty,channelResp));
but it did not work, it works only for 2D cells. Is there a solution for 3D cells?
Thanks in advance

Try this:
[r,c] = find(cellfun(@isempty,channelResp));
[nR,nC,nD] = size(channelResp);
Dep = floor(c/nC-0.0001)+1;
Col = c - nC*(Dep-1);
Row = r;
Let me know if you have doubts.

The simple MATLAB solution is to use ind2sub. First lets create some fake data:
>> A = repmat({NaN},12,125,1216);
>> A(5,23,[2,4,8]) = {[]}; % empty
Then all you need is this:
>> [R,C,P] = ind2sub(size(A),find(cellfun('isempty',A)))
R =
5
5
5
C =
23
23
23
P =
2
4
8
Why I used P: https://www.mathworks.com/help/matlab/math/multidimensional-arrays.html
