Jacobian |
Syntax |
Jacobian(L:LIST):MAT where L is a list of polynomials. |
Summary |
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] ] ------------------------------- |
