The core.matrix API should be 100% pure Clojure.
Some of the implementations are JVM specific however (e.g. support for fast
operations on Java double arrays etc.)
So... it probably needs a bit of hacking to make it work on ClojureScript
with some form of conditional compilation setup. If anyon
core.matrix, I mean.

Here is some example code

This allows you to evaluate infix or rpn expressions. It also demonstrates
the use of eval to turn the expression into a clojure function which should
give more performance.
It is very simple though, so all the elements in the expressions hav

You can evaluate expressions like this ri

You could just write this yourself.
It's easier than it looks.
First start with an evaluator for rpn (reverse polish notation) expressions.
"x + sin(y)" in rpn would be "y sin x +".
First you split that string and make it into a list.
Then you can evaluate that with a few lines of code using a stac
Thanks, I'd seen those. Incanter is jvm only, I think, which is less useful
to me. clojure-infix looks dead, but maybe I can adapt it.

Incanter has some stuff that does this:
http://data-sorcery.org/2010/05/14/infix-math/
this looks even closer to what you're looking for:

Are there any existing libs for the evaluation of math expressions? For
example, if the user enters "x + sin(y)", parse and evaluate the
expression, given vectors of floats for x and y.
