## DA.DiffSupp

Computes the differential support of a differential polynomial.

### Syntax

DA.DiffSupp(F:POLY):LIST

### Description

Computes the differential support of the differential polynomial F.

@param F A differential polynomial.

@return The differential support of F.

#### Example

Use Q[x[1..2,0..20]]; F:=x[1,4]^2-x[2,4]^3; DA.DiffSupp(F); ------------------------------- [x[1,4], x[2,4]] -------------------------------
