Witryna多元函数的Hessian矩阵就类似一元函数的二阶导。 多元函数Hessian矩阵半正定就相当于一元函数二阶导非负，半负定就相当于一元函数二阶导非正。如果这个类比成立的话，凸函数的Hessian恒半正定就非常容易理解了——这是一元凸函数二阶导必非负的多元拓展。 In mathematics, a Hermitian matrix (or self-adjoint matrix) is a complex square matrix that is equal to its own conjugate transpose—that is, the element in the i-th row and j-th column is equal to the complex conjugate of the element in the j-th row and i-th column, for all indices i and j: or in matrix … Zobacz więcej Hermitian matrices are fundamental to quantum mechanics because they describe operators with necessarily real eigenvalues.
