jacobian

the Jacobian of a list of polynomials

Syntax
jacobian(L: LIST of RINGELEM): MAT

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 ::= QQ[x,y];
/**/  L := [x-y, x^2-y, x^3-y^2];
/**/  jacobian(L);
matrix( /*RingDistrMPolyClean(QQ, 2)*/
 [[1, -1],
  [2*x, -1],
  [3*x^2, -2*y]])
