making one matrices dimension same as other

hi

I have the following matrices

h = 5.1000 3.5000 1.4000 0.2000

6.4000 3.2000 4.5000 1.5000

5.4000 3.4000 1.7000 0.2000

5.7000 2.8000 4.5000 1.3000

5.7000 4.4000 1.5000 0.4000

5.6000 2.9000 3.6000 1.3000

k = 5.1000 3.8000 1.9000 0.4000

6.4000 2.9000 4.3000 1.3000

4.3000 3.0000 1.1000 0.1000

5.4000 3.0000 4.5000 1.5000

I want to make K =

5.1000 3.8000 1.9000 0.4000

6.4000 2.9000 4.3000 1.3000

4.3000 3.0000 1.1000 0.1000

5.4000 3.0000 4.5000 1.5000

0.0000 0.0000 0.0000 0.0000

0.0000 0.0000 0.0000 0.0000

so that it has the same dimension as h. How do i do that. Thanks in advance

[rows1 colm1]=size(h);
[rows2 colm2]=size(k);
% You can change the way depending on sizes of h and k
% Also which direction you want to pad zeros
k_revise=[k;zeros(rows1-rows2,colm1)];

5.1000 3.8000 1.9000 0.4000

6.4000 2.9000 4.3000 1.3000

4.3000 3.0000 1.1000 0.1000

5.4000 3.0000 4.5000 1.5000

0 0 0 0

0 0 0 0

There are more smart way to do the same, please follow padarray

ok Kalyan

But if I want to make it 0.0000 instead of using a single 0 how do I go about it

thanks again
