In old studymaterial i could calculate  a gradient in (1,-1,2)   with obselote   package linalg 

f:= (x,y,z)->exp(x*y^3*z^2);

gradf(1, -1, 2); # werkt wel
              [-4 exp(-4), 12 exp(-4), -4 exp(-4)]

But i couldn't do it with the LinearAlgebra  or VectorCalculus package ?
LinearAlgebra has no gradient command, so left over Vector Calculus what is the right place
