how can i add two matrix vertically with different column

Hello,

how can i add two matrix vertically with different column?

please help

thank you

like this example:

A=[1 3 6 8 9]

B=[1 2]

Result= 1 3 6 8 9

What have you tried already? What problems do you have?

i used of vertcat and get me this error:

Error using vertcat

Dimensions of matrices being concatenated are not consistent.

Answer 1

[madhan ravi]

m = max(numel(A),numel(B));
% Method 1 
Wanted = reshape([A(:);B(:);zeros(m-numel(B),1)],[],2).'
% Method 2
w = cellfun(@(x)[x,zeros(1,m-numel(x))],{A,B},'un',0);
Wanted = cat(1,w{:})
% Method 3
Wanted = zeros(2,m);
Wanted(1,:) = A;
Wanted(2,1:numel(B)) = B
% Method 4
Wanted = [A;B,zeros(1,m-numel(B))]

Thank you very much for helping me.

It was very useful

Answer 2

Bpad = padarray(B,[0,numel(A)-numel(B)],'post'); 
C = [A;Bpad]

I would do with the old well-served for-loop

C={A B}; % put the list of your matrices here

m=cellfun('size',C,1);
n=cellfun('size',C,2);
Results=zeros(sum(m),max(n));
r=0;
for k=1:length(C); 
    Results(r+(1:m(k)),1:n(k))=C{k}; 
    r=r+m(k); 
end
