MATLAB: Access cell array inside another cell array

Question

Hello,

I have a 50×1 cell array. Each cell is a 2×1 array.

A = {2×1 cell;

   2x1 cell;
   2x1 cell
   etc}

if I get into every cell I have cell = {a b}

I am trying to access each string in the 2×1 cell for all rows (a and b).

So if my array is called A this is the function I am using to extract the each column of the inside cell for all rows:

A = cellfun(@(x) x{:,1}{:,1}, A, 'UniformOutput',0)

B = cellfun(@(x) x{:,1}{:,2}, A, 'UniformOutput',0)

I am getting the following error: "Cell contents reference from a non-cell array object".

I was wondering if anyone can help me accessing those two columns of my multiindex cell array.

Thank you very much

The anonymous function used in cellfun is applied to each element of A, so the input it expects in your case would be a 1 x 2 cell of strings, not the parent cell array of cell arrays:

a = cellfun(@(x) x{1}, A, 'uni', 0);
b = cellfun(@(x) x{2}, A, 'uni', 0);
