How to take derivative of a vector in matlab
WebDerivatives with respect to vectors Let x ∈ Rn (a column vector) and let f : Rn → R. The derivative of f with respect to x is the row vector: ∂f ∂x = (∂f ∂x1,..., ∂f ∂xn) ∂f ∂x is called the gradient of f. The Hessian matrix is the square matrix of second partial derivatives of a scalar valued function f: H(f) = ∂2f ∂x2 ... WebApr 4, 2014 · I can define the following vector function. f(x, y, z) = [x 2 - 1, x 3 + y 2, z] In MatLab or in Maple. I want to find (and evaluate) the first, second and third derivatives of it. How to find: ∇f, ∇ 2 f and ∇ 3 f? Here vector function f is differentiated with respect to vector (x, y, z). I can do the simple job of finding ∇f with Maple ...
