Let $X$ be a complex manifold of complex dimension $n$, and let $h$ be a Hermitian metric on the holomorphic tangent bundle $T^{1,0}X$. Let $(U,z)$ be a holomorphic coordinate chart with coordinates $z=(z_1,\dots,z_n)$, and write the local frame of $T^{1,0}X|_U$ as $e_i=\partial/\partial z_i$. Define the Hermitian matrix-valued function $H:U\to \operatorname{Herm}_n(\mathbb{C})$ by
