All are from this post.
What does these statement mean:
error(nargchk(5, 6, nargin));
plot(p(:,1), p(:,2), '.-'), axis equal
And what's this kinda syntax which I haven't quite often seen:
if nargin<6, steps = 36; end

I hope I don't come over as too unhelpful, but have you tried:
- using Matlab's built-in help facilities to discover for yourself what the various statements mean ? or
- running any of the code ?
All the statements are Matlab intrinsics and well documented. The use of , to separate statements on the same line is a bit unusual (I, for one, would usually put the statements on different lines in your examples), but not incorrect

Can you explain what's the difference of `,` and `;` in `if nargin<6, steps = 36; end`? – user198729 Apr 12 '10 at 10:39
