# jackpolynomials
Schur polynomials have applications in combinatorics and zonal polynomials have
applications in multivariate statistics. They are particular cases of
[Jack polynomials](https://en.wikipedia.org/wiki/Jack_function). This package
allows to evaluate these polynomials. It can also compute their symbolic form.
```haskell
import Math.Algebra.Jack
import Data.Ratio
jack [1, 1] [3, 1] (2%1)
-- 48 % 1
```
```haskell
import Math.Algebra.JackPol
import Data.Ratio
import Math.Algebra.Spray
jp = jackPol 2 [3, 1] (2%1)
prettySpray show "x" jp
-- "(18 % 1) * x^(1, 3) + (12 % 1) * x^(2, 2) + (18 % 1) * x^(3, 1)"
evalSpray jp [1, 1]
-- 48 % 1
```
