Details:

When using the polar command to plot, it draws an axis with 0 - 360 deg shown.
The documentation also uses degrees. But it is assuming that the input data is
in radians.


q=rand(1,100);
c=ones(1,numel(q))*2; # a vector of 2s
polar(c,q,'.')


This should draw a line at 2 degrees but it is a 2 radians.
We can change the documentation or the calculations.
