Ok, here's what you're missing in this example:

function a = myRand
 a=1+rand(3,4)*9;
end

Now your function has an output-variable, a, that the function will return when called. You can also have multiple output-variables:

function [a,b] myRand
 a=1+rand(3,4)*9;
 b = sin(a);
end

For the cases where that is prefereable.

Since you are a beginner you might consider looking over the "on-ramp" material on the site: on-ramp.
