You want to count how many cells are in each element of the cell array?

```     x = cell(3,1);
x{1} = cell(2,1); x{2} = cell(25,1); x{3} = cell(30,1);
out = cellfun(@numel,x,'uni',0);
numberofelements = sum(cell2mat(out));```

In the above, cellfun() gives you cell array with each cell containing the number of elements in each cell of your original cell array.

cell2mat() turns that cell array into a vector, so now you have a vector where each elements gives the number of each elements in the cell arrays of your original cell array.

Finally, I just sum the elements of the vector to get the total number of elements.
