ellheight tutorial


Hi,

Since the rewriting of the ellheight0() function, the example at end of p.27 of the Tutorial has become inadequate.

It should (at least) read:

hv = ellheightmatrix(e, v)
...
perm = vecsort(vector(#v,i,i), (a,b) -> hv[a,a]>hv[b,b]);

to prevent an "incorrect type" error...

Best regards,
