i have a cell array with values
cellarr = {'a','b','c',3,5;'b',5,'a',[],[];'a','c',3,'a',4;'b','a','c','c',3};
i wanted to find the location where a particular number or string occurs
for example i want to get the location where the number = 3
so my expected output is
1st row 3rd column
3rd row 3rd column
4th row 5th column
[row,col] = find(___)
i want both the row and column position as it comes for find function
find not working with cell array

After using find(), you just need to convert the linear index into row and col index, see ind2sub

You need to use a bit of trickery to use find (ismember will not work normally either).
cellarr = {...
'a','b','c', 3 ,5;...
'b', 5 ,'a',[] ,[];...
'a','c', 3 ,'a',4;...
[row,col] = find(cellfun(@(x) isequal(val,x),cellarr));
ans = 3×2
3 3 1 4 4 5

This is the default order for find, but you can use sort (and its second output) to sort on row instead of column.
