hessian矩阵
5星 · 资源好评率100%
在Matlab中,可以使用"hessian"函数来求解Hessian矩阵。该函数的语法为:hessian(f, vars),其中f是多元函数,vars是函数中的变量。例如,对于一个三元函数f(x, y, z),可以使用以下代码来求解Hessian矩阵:
syms x y z;
f = x^2 + y^2 + z^2 + y*z*x;
H = hessian(f, \[x, y, z\]);
这样,变量H就是求得的Hessian矩阵。请注意,Hessian矩阵是一个二阶偏导数构成的雅可比矩阵,它描述了多元函数在某一点处的曲率和二阶导数信息。\[1\]\[2\]
