How to add constant values above and below of each columns of a matrix?

Hello,

I have a matrix say VP of size 100 * 106 and I want to add 50 constant values above and 50 values belowhis matrix (50 values on each column above and below) . How can I do it?

Answer 1

[Kevin Holly]

VP = rand(100,106);
extra50 = rand(50,106);

NewVP = [extra50;VP;extra50];

size(VP)

ans = 1×2

100 106

size(NewVP)

ans = 1×2

200 106

thanks @Kevin Holly, instead of random, how can I use a constant number.

[John D'Errico]

extra50 = repmat(pi,50,106);

or

extra50 = pi*ones(50,106);
