MATLAB: Find empty cells in 3D cell

empty cells

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.

 C = {0:3, 4:5, 6:9};
 out = NaN(size(C));
 for k = 1:numel(C)
     out(k) = mean(C{k});
 end

or if the outputs are non-scalar, then put in a cell array:

 out = cell(size(C));
 for k = 1:numel(C)
     out{k} = mean(C{k});
 end

Hello Sarah,

You can count the empty cells using the following commands

N_nonempty = find(~cellfun(@isempty,Out));
count_empty = length(Out)-length(N_nonempty);
