Plotting Cartesian Product of two infinite sets

The problem regarding plotting of Cartesian product of two finite sets have been dealt with previously in this forum. My concern is that I have two infinite sets and I want to plot the cartesian product of that. For example :$X = {t \in \mathbb{R} | (2cos(t) , 3sin(t))}$ and $Y = {x | 0 \leq x \leq 1}$ and I want to plot X x Y. What is the way to do it ? I am using MATLAB for the plots. But I have access to python , Scilab and R too.
