finding the Hessian (third order tensor) and higher order derivatives
Hi I want to know whether it is possible to obtain the third order tensor (second derivative) and
also the higher order derivatives in Maple just as we can find the Jacobian. Then how?
For example, x=array(1..n): f:=[x[1]^2-2x[2], x[2]^3-3x[3]]: jac:=jacobian(f,x);
we can get the jacobian.
Can we get the second derivative (n by n by n matrix) and also the higher order derivatives. Thanks.
