Thanks for your report.

Can you come up with a patch, or even better, a Mercurial changeset, if possible with some tests?

rotv([0,0,1],pi()/2) (which is assumed to be a PI/2 rotation about the z+ axis) returns:

  1. 1 0

-1 0 0

  1. 0 1

as apposed to the correct result:

  1. -1 0

1 0 0

  1. 0 1

Which is the inverse what rotv returns. It appears that this also occurs for rotv([1,0,0],-pi()/2).
