Counting amount of digit occurrence in a cell

I have this cell just with simple numbers, and I would like to count how many times each digit is repeated in this whole celll, so for example if this one would've had just 9 rows, as an output I'd like to see that i have seven two's, one three and one nine.

I've just found the answer:

1) I changed it into regular array

cell2mat(GOid_ALLProteins)

Then i used

[GC,GR] = groupcounts(x) 

which i found as an answer for similar question there:

Try something like this —

CellArray = num2cell([2; 2; 2; 2; 2; 2; 2; 3; 9]);
[Uc,~,ix] = unique([CellArray{:}],'stable');
Count = accumarray(ix,1);
Col1 = Uc(:);
Result = table(Col1,Count)

Result = 3×2 table
    Col1    Count

     2        7  
     3        1  
     9        1
