Hi Luis,
Any unexpected behaviour is worth asking about, so thank you (as so often)! In
particular, anything that breaks an expectation of being able to chain
operations in an OO style is bad.
I’ve just pushed what I believe is a fix on GitHub, so please give that a go if
you like. I’m holding
Hi Ed,
Thanks for looking at this. It was not too important, but it was
surprising, as I was chaining pdl methods (...->det->approx(0) to
detetct singular matrices) and I was getting somewhat strange error messages
as det was sometimes an ndarray and other times a scalar.

Hi Luis,
The key (if you’ll forgive the pun) is the behaviour of the “det” function,
which is (at this writing) defined in Basic/MatrixOps/matrixops.pd as:
sub det {
my($x) = shift;
my($opt) = shift;
$opt = {} unless defined($opt);
my($lu,$perm,$par);
