How to concatenate horizontally

[SriRajesh]

Hi,
I have below two matrices:
a=2
b=4
I want to concatenate them horizontally:

my desired  output:
2
4

Many thanks in advance,

Those looks like regular ints, not matricies (unless they're 1x1 matrices for some reason?). Any reason you can't just print them one after the other?

It could be something lost in translation but for me an output of
2
4
is 'vertical', whereas
2 4
is horizontal
