Question

What is the purpose of this command in MATLAB?angles=[-90:180]*p...

Answer 1

The command first creates vector containing [-90 -89 -88 ... 178 179 180]

There are 271 elements in the vector.

That entire vector is then multiplied by pi/180, resulting a 271 element vector containing [-1.5708 -1.5533 -1.5359 ... 3.1067 3.1241 3.1416]

Oh, by the way, you might want to insert a semicolon after the command like this:

angles=[-90:180]*pi/180;

Otherwise, Matlab will spew all 271 values to your screen
