Question

I would like to add two vectors with different lengths in Matlab or Octave. E.g.

aa = [1 2 3 4];
bb = [100 100];

Which should result in a vector cc containing

cc = [101 102 3 4]

Can anyone figure out how to do this?

Update: This is the code I ended up with for the signals that I then later convert to grey scale images.

load train;
t = y;
load chirp;
c = y;

tc = c + [t; zeros(length(c) - length(t),1)];

plot(1:length(tc),tc)

Thank you very much to you all =)

Answer 1

This doesn’t make any sense mathematically, but if you insist, you can do this:

cc = aa + [bb zeros(1,2)];
