Hessian matrix of a scalar function

MuPAD® notebooks are not recommended. Use MATLAB® live scripts instead.

MATLAB live scripts support most MuPAD functionality, though there are some differences. For more information, see Convert MuPAD Notebooks to MATLAB Live Scripts.


hessian(f, x)


hessian(f, x) computes the Hesse matrix (the Hessian) of the scalar function in Cartesian coordinates, i.e., the square matrix of second partial derivatives of .


Example 1

The Hessian of the function f(x, y, z) = xy + 2 xz is the following matrix:

delete x, y, z:
hessian(x*y + 2*z*x, [x, y, z])

For a function , X a subset of , the p×p matrix

is called the Hesse matrix of f.
