Jacobian
the Jacobian of a list of polynomials
Description
This function returns the Jacobian matrix of the polynomials in L
with respect to all the indeterminates of the current ring.
Example
Use R ::= Q[x,y]; L := [x-y, x^2-y, x^3-y^2]; Jacobian(L); Mat([ [1, -1], [2x, -1], [3x^2, -2y] ]) -------------------------------
Syntax
Jacobian(L:LIST):MAT where L is a list of polynomials.
