NoetherianOperators :: evaluate(DiffOp,Point)

evaluate(DiffOp,Point) -- evaluate coefficients of a differential operator

Synopsis

Description

Evaluates the polynomial coefficients of a differential operator at a point. This can be used to obtain a set of specialized Noetherian operators.

i1 : R = QQ[x,y];
i2 : S = diffOpRing R;
i3 : D = diffOp(x*dx+y*dy^3)

o3 = | ydy^3+xdx |

                1
o3 : DiffOp in S
i4 : evaluate(D, point{{1,2}})

o4 = | 2dy^3+dx |

                1
o4 : DiffOp in S
