MATLAB: Take specific elements from each cell of a cell array

cellcell arraycell arraysvector

Hello! Let A be a 1×10 cell array. Each of the 10 cells of A are nxm matrices.

Also, let an 1×10 vector x, that is, x=[ x1 x2 … x10 ].

I would like to take the x1 row from the first cell of A, the x2 row from the second cell of A, and so on for all the 10 cells of A.

I have tried cellfun, but I did not achive my goal.

Thanks in advance.

cellfun(@(a, X) a(X,:), A, x, 'uniform', 0)

MATLAB: Apply logical cell to a cell

result = cellfun(@(a, b) a(b), A, B, 'UniformOutput', false)

will produce a 100x1 cell array of vectors (since filtering a matrix with a logical array always result in vectors).

MATLAB: Transposing cells

Do you mean that each cell in the cell array contains a matrix, and you want to transpose each matrix? If so, then you need the cellfun command:

% Fill the cell array
a{1} = [1 2; 3 4];
a{2} = [5 6; 7 8];
% Display the cell array before the transpose
a{:}
% Do the transpose
a = cellfun(@transpose,a,'UniformOutput',false);
% Display the results
a{:}
