Given two vectors x,y, in 2D or three vectors x,y,z in 3D space, compute the area (or volume) of the parallelogram they define.

For example:

X=[0,1]'; Y=[1,0]'; 
V = 1;

X=[1,0,0]'; Y=[0,1,0]'; Z=[0,0,1];

When did the "function ans = " trick start working again?

It started to work when Cody server upgraded its MATLAB to R2016b. So strictly speaking, it's not just a Cody trick, but a MATLAB R2016b feature. This feature was somewhat discontinued in R2016a, but it works in many earlier versions.
