[Octave-bug-tracker] [bug #56069] [octave forge] (symbolic) Laplace transform of sin(w*t) gives wrong value

[Colin Macdonald]

Follow-up Comment #3, bug #56069 (project octave):

It is valid.  I originally thought symvar made more sense b/c that's how other
places do this magical lets-guess-the-independent-variable game...

In the code there are comments like:

t = symvar(f, 1);  % note SMT does something different, prefers t
...
% matlab SMT prefers t over x (WTF not symvar like we do?)


I can think of two "fixes":
1.  We move the comments up to documentation.
2.  We research what Matlab SMT does and try to duplicate it.
Pesumably they fall-back on symvar if they don't find t (?)

My $0.02: relying on this magic stuff is insane for anything remotely serious;
Mike's "workaround" is The Right Way.  But I suppose we might as well be
insane in the same way as Matlab's SMT.
