MATLAB: Generating a vector containing the sizes of all cells of a cell array, along a specific dimension

size cell array cellfun dimension

Is there a way to vectorize this? (I tried with "cellfun", but did not succeed).

for i = 1:numel(a)
    s(i) = size(a{i}, 1);
end

Where a sample of "a" is provided in attachment.

Does this give what you want?

s = cellfun(@(x)size(x,1),a);

MATLAB: Concatenating cell arrays with a different number of columns

maxcols = max(cellfun('size', NonC_tRNAs, 2));  %get the number of columns of the widest array
padded = cellfun(@(m) [m, zeros(size(m, 1), maxcols - size(m, 2))], NonC_tRNAs, 'UniformOutput', false);  %pad each array
NonC_tRNAs_Reference  = vertcat(padded{:})

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{:}
