If the task were to write a function that multiplies each element of a vector or matrix (or any array) by 2, then a solution might be:

function out = mult2(in)
out = in*2;
end

I'll let you figure out from that how you might go about writing a function that adds 1 to each element of a vector or matrix.

This may be of use as well:
