What is the largest vector that you can work with on your computer in MATLAB? What is the largest matrix? (Try different n and observe for which n MATLAB starts screaming at you, or for which n you have to wait an inordinate amount of time). You can follow these examples:

n=10;

x=rand(n,1);

n=10;

A=rand(n,n);

Do the same for PYTHON and NUMPY. Compare the timings to those in MATLAB. (Here you may want to use the actual wall clock time observed with your own watch).
