Comment:
The matrix of the isometry that sends the geodesic to the imaginary axis
is a symbolic array, when this matrix is numeric the algorithm evaluates
efficiently but when is purely symbolic it is necessary a double
full_simplify() operation so that the posterior operation of inverting the
matrix does not get a runtime error. After profiling the code, I do not
see (surprisingly) any speed advantage in coding explicitly the inverse
matrix, so I decided to left that unchanged.

order to avoid the runtime error.}}}||
