MATLAB: Concatenate

concatenation

Dear matlabians

I have a cell variable z = (hello1 hello2 hello3) another cell variable y = (bye1 bye2 bye3) and a double x = (1;2;3 , 4;5;6 , 7;8;9)

how i can I concatenate them in a 5×3 vector

v = (hello1;bye1;1;2;3 , hello2;bye2;4;5;6 , hello3;bye3;7;8;9)

thank you

This makes the 5x3 that you requested.

c1 = {'hello' 'world' 'Happy Tuesday'};
c2 = {'Need' 'coffee' 'now'};
m1 = magic(3);
C = vertcat(c1,c2,num2cell(m1));

To make a 3x5 use;

C = horzcat(c1',c2',num2cell(m1));

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{:}

Or a loop:

for k = 1:numel(C)
  C{k} = C{k}.';
end

[EDITED] Accroding to your comment:

M = [1 2 3;  4 5 6;  7 8 9];
C = mat2cell(M.', 3, [1,1,1]).';
{[1;2;3]; 
 [4;5;6];
 [7;8;9]}

Or again with a simple loop:

C = cell(3, 1);
for k = 1:3
  C{k} = M(k, :).';
end
