Hi

I have a cell array, 1x 90. eacht of them has diff set of data,

for example, 1x1 has 10 cells , 1x2 5 cell etcs.

i want to count to count the amount of cells

numel(cellarrayname) gives 90... thats not what i want.

it should count every cell array add cellarray 2 +cell aray 3 etc..

Accepted answer

your_count = cellfun(@(x) numel(x),your_cell_array);

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.
