## diffalg.PseudoReduce

Returns a pseudo normal form of a polynomial wrt. a given set of polynomials.

### Syntax

$diffalg.PseudoReduce(F:POLY, G:LIST):POLY

### Description

PseudoReduce computes the pseudo normal form of the differential polynomial F wrt. the list G of differential polynomials.

#### Example

Use Q[x[1..1,0..20]]; Use Q[x[1..1,0..20]], Ord($diffalg.DiffTO("Lex")); $diffalg.PseudoReduce(x[1,1]^4+x[1,0], [x[1,0]^2+3x[1,0]]); ------------------------------- 9 -------------------------------
