I have this Cell Array ‘A’ of size 3 by 7

A = { 3 4 [] [] [] [] []

2 6 -2 2 -2.1 2 2

-5 -5 25 1 [] [] []}

I want to find index of ‘6’ element in 2nd row and 2nd column The answer shall be row = 2 and column = 2

isSix = cellfun(@(x)isequal(x,6),A);
[row,col] = find(isSix);

Not at all intuitive, but it works great, even for logicals.

Re-using the framework of my answer to your earlier question:

B = A;
B(cellfun(@isempty, B)) = {NaN};
[maxrow, maxcol] = find( reshape(cell2mat(B), [], 1)  == 6);

Looking again several years later, it looks like the code should use

[maxrow, maxcol] = find( cell2mat(B) == 6);
