Matrix Row Addition Question

Good evening all!

I have a quick question. I am attempting to create the follow matrix in MATLAB:

0 0 0 0 0 0

0 0 0 0 0 0

0 0 8 6 4 2

I am completly new to MATLAB and I am just learning about matricies. My question is in regards to how do I create the last row? I was able to create the first two using the following command:

k= [zeros(2,6); ]

I would have used a linspacing command but those first two initial 0s prevent that. Thanks again for your help. I am just trying to honestly learn how to code in this language.

There are several ways to do what you want.

Here’s one:

k = zeros(3,6);
k(end, 3:6) = 8 : -2 : 2;

Thank you for your help! What if I was attempting to complete it in one line?

As always, my pleasure!

In one line:

k = [zeros(3,6); 0 0 8 : -2 : 2];

This is ‘vertical concatenation’.
