Access cell array inside another cell array
显示 更早的评论
Hello,
I have a 50x1 cell array. Each cell is a 2x1 array.
A = {2x1 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 2x1 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);

Either a) one of the internal cell arrays wasn't a 2 x 1 cell array, or b) you save that first output as A (as in your example above), thus replacing your original A.
