Wikipediajacobiang(f)
Returns the Jacobian of function f with respect to the given list of variables.
See also jacobian jacobiant partial divergence laplacian curl
Example
f(x,y,a,b)=(x*y+a, -b*sin(x*y)
f(x,y,a,b)=(x*y+a, -b*sin(x*y)
J=jacobiang(f, "x", "y")
J(x, y, a, b) = ( y, x ; -b*cos(x*y)*y, -b*cos(x*y)*x )
