Question

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

1 2 0 0 0

Answer 1

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))]
