See this link for a discussion of various methods to do this:

The fastest method seems to be

z = zeros(length(x),1) + 2;

To create arrays with the same number I'd personally just set a variable and put it in the linspace function

x = 3
poof = input('how many columns of this number do you want?')
linspace(x,x,poof)
