Thanks for the many helpful suggestions. Pure Aldor might be an interesting
avenue. For prototyping
I will probably first use the interactive mode or SPAD, and then think
about pure Aldor vs. an ECL or pipe route.
In that regard I have a few additional questions:
- When using Aldor programs within FriCAS, do I get access to all domains
and categories within FriCAS,
or is it a limited subset? Is it documented which ones are available?
Concretely I am interested in Puiseux series.
Looking at the source, the Aldor algebra library does seem to have at least
a Taylor series. To make it clear:
as a first step I would be interested in writing Aldor programs (instead of
SPAD) and load them in FriCAS (with ")compile"), so
not standalone Aldor programs.
- Is UnivariatePuiseuxSeries(Expression(Float), 'x, 0.1::Float) something
that is not well-defined, or is it just not implemented?
-> series((0.1::Float)*x,x,0.0::Float)
...
Cannot find a definition or applicable library operation named
series with argument type(s)
Polynomial(Float)
Variable(x)
Float
Thank you,
Tobias
