Thanks very much, @tbreloff. However I fear my newbie status is proving a problem. This may be because I’m coming at the problem from a Matlab perspective.
- The attributes reference is an abstract description which I find difficult to understand without a concrete example.
- I’m unclear from your inline example “quiver(x, y, quiver=(u,v))” what exactly the various arguments are. From a Matlab point of view I’d expect x and y to be meshgrids, however I see that in the contour plots you use linspaces instead. When I use meshgrids I get a load of error messages, and when I use linspaces, I only get arrows on a leading diagonal of points (1,1), (2,2), … Should I be using tuples?
- In the first example in the notebook you only use a single position variable y.
- In the second notebook example you use vec(), which I’ve just looked up and understand, but not why you use it. You also use P2, which I can’t find in the documentation.
Help?
