Hi Marc,

Take a look at:

https://github.com/soegaard/racket-cas

Start with the readme and play with a few examples.

Skim (later parts) of:


https://github.com/soegaard/racket-cas/blob/master/racket-cas/racket-cas.rkt

to see what's implemented.

Any bug reports and comments are welcome.

Re: [racket-users] Feasibility of Racket for scientific and engineering calculations

2015-11-12 Thread Marc Kaufmann 
Since you mention symbolic computations: is there anything that does symbolic 
differentiation in Racket - I know Maxima is written in Common Lisp. I would I 
would be happy with only differentiation and little of the other stuff, if only 
to check my own computations (in economics) as I have perform a sign-error in 
25% of the cases...

A few useful resources:

Matrices
http://docs.racket-lang.org/math/matrices.html?q=matrix

GNU Scientific Library

http://planet.racket-lang.org/package-source/wmfarr/mzgsl.plt/3/0/planet-docs/mzgsl/index.html

Science Collection

http://planet.racket-lang.org/package-source/williams/science.plt/4/8/planet-docs/science/index.html

Math library
http://docs.racket-lang.org/math/index.html?q=matrix

Also: If you are looking for concrete algorithms - just ask. Chances are
that
someone has a Racket and/or Scheme implementation lying around.

If you are interested in symbolic computations I have a few ideas.

[racket-users] Feasibility of Racket for scientific and engineering calculations

2015-11-02 Thread John Kitchin 
Hi all,

I am exploring whether Racket could be a Lisp replacement for Python in 
scientific and engineering calculations. I currently use Python extensively in 
teaching chemical engineering courses 
(http://kitchingroup.cheme.cmu.edu/pycse/) and in running molecular simulations 
(http://kitchingroup.cheme.cmu.edu/dft-book/), but I am interested in 
transitioning these to a Lisp.

Why? Because I really like writing Lisp code, and some interesting things I can 
do with it. My current experience is all with emacs-lisp, which at the moment 
has no hope for replacing Python as it lacks a real ffi.

Python works for scientific/engineering calculations because of 
numpy/scipy/matplotlib which provide the majority of our needs, and largely 
they just wrap C/Fortran numerical libraries. It is also distributed with 
batteries included that make it trivial to install these days. It seems like 
Racket can do this too.

How feasible would it be to use Racket to solve the problems described here: 
http://kitchingroup.cheme.cmu.edu/pycse/pycse.pdf

I am trying to gauge how difficult it would be to start using Racket for these 
problems. Does anyone know of any similar kinds of projects as my Python 
project above in Racket?

Thanks!
