MATLAB: Mean of each column of a cell array that contains cell arrays

cell arrays

I have a cell array A(2×82). Cell array A contains in each cell cell arrays of different row sizes but equal column sizes. To be specific the column sizes are always 1.

First I want to combine the two rows of A and then calculate the mean of each column of cell array A. As a result i would get a 1×82 matrix.

Any suggestion? Thanks in advance, Peter

cellfun(@mean, A)     %provided you want a 2 x 82 numeric result.

MATLAB: Combine a cell array of cell arrays to a single cell array

NewCellArray = vertcat( ExistingCellArray{:} );

MATLAB: Apply the same function into several columns

Use a loop:

B = zeros(1, size(A, 2));
for column = 1 : size(A, 2)
    B(column) = yourfunction(A(:, column));
end

Or you can use cellfun, which is just a loop in disguise:

B = cellfun(@yourfunction, num2cell(A, 1));

edit: That's assuming the function cannot already operate on the columns of the whole matrix, as pointed out by Star.
