Releases · flatsurf/intervalxt

Added:

IntervalExchangeTransformation::equivalent() method to decide whether two
interval exchange transformations are equivalent modulo the precise labeling.
The Lengths of an IntervalExchangeTransformation are not available as
iet.lengths in Python. This is probably limited to interval exchange
transformations originally created through the Python interface.

Changed:

Split ::intervalxt::sample::Arithmetic into
::intervalxt::sample::FloorDivision and
::intervalxt::sample::Coefficients. The latter now accepts a vector of
elements and produces a vector of Q-vectors that correspond to the given
elements after being brought into the same vector space. This is a breaking
API change.
The method Lengths::coefficients() now expects a vector of labels and
produces a vector of Q-vectors corresponding to realizations of the
corresponding lengths in a common Q vector space.
The method IntervalExchangeTransformation::safInvariant() now returns a
vector<mpq_class> instead of a valarray<mpq_class>. The valarray had
always been a source of issues since it does not play nicely with vectors
that we use everywhere else in the flatsurf stack.
In the Python interface, IET has been renamed to
IntervalExchangeTransformation and makeLengths to Lengths.
sample::Lengths over integer types now require gmpxxll to be available.

Fixed:

Most labels now print nicely in the Python interface.
negative lengths are now detected in the Python interface and reported as an error, #85
