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.
