Description: Matlab中没有现成的Hermite插值函数，必须编写一个M文件实现插值。
设n个节点的数据以数组x0 （已知点的横坐标）， y0（函数值）， y1（导数值）输入（注意Matlat的数组下标从1开始）， m个插值点以数组x 输入，输出数组y 为m 个插值。编写一个名为hermite.m的M文件。
-Matlab is not off-the-shelf Hermite interpolation function, we must realize the preparation of a document M interpolation. N nodes for the data to an array x0 (known point of abscissa), y0 (function value), y1 (numerical derivative) input (note the subscript Matlat array starting at 1), m to the array of interpolation points x input and output array y for m months interpolation. Hermite.m the preparation of a M-file. Platform: |

Description: 基于三次埃尔米特多项式推导出来的三次样条插值matlab程序，用于知道一阶导数边界条件的插值，不仅可以输出插值节点的值，还可以输出每一段的插值多项式，更重要的是还可以输出各插值点的一阶导数值。-This is a matlab code of cubic spline interpolation, which is derived the Hermite of three polynomials. It can be used only when the first derivative of boundaries is known. This code can not only output the value of the interpolation node, it can also output every interpolation polynomial, more importantly, it is also can output the first derivative of each interpolation point.
