## DA.DiffAutoReduce

Computes a reduced list of differential polynomials.

### Syntax

DA.DiffAutoReduce(G:LIST of POLY):LIST of POLY

### Description

DA.DiffAutoReduce computes for a given set G of differential polynomials a list of reduced differential polynomials H, s.t. every element of G reduces to zero wrt. H.

@param

*G*A set of differential polynomials.@return A list of reduced differential polynomials.

#### Example

Use Q[x[1..1,0..20]]; Use Q[x[1..1,0..20]], Ord(DA.DiffTO("Lex")); DA.DiffAutoReduce([x[1,2]^2+x[1,0]^2+3, x[1,1]+3x[1,0]]); ------------------------------- [x[1,1] + 3x[1,0], 82x[1,0]^2 + 3] -------------------------------
