数学计算中的埃尔米特C源代码，能够解决实际问题中要求在节点上函数值相等，还要求导数值相等，甚至要求高阶导数值也相等的插值问题-Mathematical calculations Hermite C source code required to solve practical problems on a node is equal to the function value, also called derivative values are equal, or even require higher-order derivative values are equal to the interpolation problem
