Counting number of nonempty cells within a cell

27 views (last 30 days)
I have a 32x3 cell and I want to count the number of nonempty cells within it. When I use N = nnz(my_cell), this is the error I get
Undefined function 'nnz' for input arguments of type 'cell'.

nnz(~cellfun(@isempty, my_cell))

nnz(cell2mat(my_cell));%assuming each cell is a number

Attach your cell array.
for k=1:32;
for m=1:3;
a{k,m}=randi(30,1)-1;%a is a 32x3 cell array of numbers
end
end
N=nnz(cell2mat(a))
N = 94

The question is not about nonzero cells, it is about nonempty cells, in a context where cells might contain different number of entries each. For example, length 5, length 0, length 3
