Hi I have a matrix like
a=[11 12 113 14
21 22 23 24
31 32 33 34
41 42 43 44]
and I want to extend it to
b=[11 12 13 14 0 0
21 22 23 24 0 0
31 32 33 34 0 0
41 42 43 44 0 0
0 0 0 0 0 0
0 0 0 0 0 0]
how can I do that with a one line command? thank you

@ss: Did you see, that there were no linebreaks in your question? I've formatted this, because it was not clear if a and b are vectors or matrices.

Or:
a(6,6) = 0;
This fills the rest with zeros automatically.

Try this
a = [a zeros(1, 14)];

If you have the Image Processing Toolbox, you might be interested in the padarray() function.
