All the code provided in this item resumes to the attached diff.

I've tested it by flipping the centered variable by hand and it works as described. One can use the following script to better understand what the effects are:


[x,y] = meshgrid(1:2:20);
plot(x,y,'*');
hold on;
quiver(x,y,x,y);


This item needs FURTHER WORK.

The attached functions do the same as their counterparts without the leading c with the only difference that the arrows drawn are centered instead of starting at the grid points.

While I first planned to pass an additional first argument named 'centering' to the original _quiver.m_, I got somewhat tangled in the varargin numbering, and since I really didn't have the time to track it down, I ended up duplicating the whole code to _cquiver.m_ for only a few changes.

I left the 'centering' logic in place, to facilitate replacing _quiver.m_ by _cquiver.m_. It really shouldn't be a big deal for anyone who finds the time to adapt the varargin stuff.
