Function returning two vectors

Couldn't really find anything on google by searching for 'functions' and 'vectors' etc, so I'll try here.
If I needed a function returning two vectors (of different size), like this:
[vec1, vec2] = functionname(variables,...)
what is the best approach? If I try to transpose them I get an error since the dimensions don't agree, and if I return them as a vector that would make it difficult to get all the elements (unless there is some trick I have not thought about). Both vectors are about 50 elements long.
Thanks.

People do that everyday using Matlab. Copy the following into a file called MyFun.m
function [y1,y2]=MyFun(x1,x2)
% input argument x1 and x2 are not used in this example
y1=rand(1,50);
y2=1:100;
Then, in Matlab command window, type
[z1,z2]=MyFun(1.1,2.2)
You get two return vectors in different size.

Even MATLAB functions do this sometimes:
[K,H,J] = unique(round(rand(1,6))) % Compare lengths of H and J.
