Comment:

 I tried compiling the example, but it doesn't build anymore with the
 latest `hmatrix`. I tried installing a few old versions of `hmatrix`, but
 none build with HEAD.

 Greg, if this problem is still relevant to you, can you please provide an
 updated version of your code that builds with the latest libraries?
