MATLAB - find multidimensional indices of entries located in nested cell array
2
In MATLAB, say I have a cell array as follows:
cell_arr = 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'a', 'b', 'c';
I want a way to find all locations in the cell array where e.g., 'a' occurs. So something like
where(cell_arr, 'a'); % returns e.g., [[1 1] ; [3 1]]
How can I do this?
Thanks for any help.

Are the contents of the cell arrays actually single characters like this or are they potentially words or multi-character strings?

They are words in the form of char vectors. So, not single characters. Thanks.

This solution may not be simple but it will work. Basically, just loop through each cell in the multidimensional cell array and find the location of the word:
function location = where(cell_arr, word)
% initialize location
location = zeros(sum(char([cell_arr:]) == word),2);
% loop through cell_arr to find the location
count = 0;
for i = 1:length(cell_arr)
for j = 1:length(cell_arri)
if cell_arrij == word
count = count + 1;
location(count,:) = [i j];
end
end
end
end
Example
where(cell_arr, 'a')
Output:
ans =
1 1
3 1
