实验一：三次样条插值（P56，例6）
一、实验目的：
1) 掌握三次样条插值的运用
2) 了解拉格朗日插值在高次上的误差
二、实验环境：Matlab6.5
三、实验内容：
1) 给定函数f(x)=1/(1+x2)，-5<=x<=5，节点xk=-5+k，(k=0,1,2…10)，用三次样条插值求S10(x)，S10’(-5)=f’(-5)，S10’(5)=f’(5)。
2）作原函数f(x)，拉格朗日插值函数Ln(x)，三次样条差值函数Sn(x)。画出三个函数的图像，比较它们的区别。
(Experiment I: cubic spline interpolation (P56, cases of 6) First, the experiment was: 1) cubic spline interpolation to master the use of 2) understanding of Lagrange interpolation in high-error second, experimental environment: Matlab6 .5 c, experimental elements: 1) a given function f (x) = 1/(1+ x2),-5 <= x <= 5, node xk =- 5+ k, (k = 0,1,2 ... 10), using cubic spline interpolation for S10 (x), S10 (-5) = f (-5), S10 (5) = f (5). 2) for the original function f (x), the Lagrange interpolation function Ln (x), cubic spline difference function Sn (x). Draw the three functions of images, compare the difference between them.)

说明： 利用BP神经网络设计指纹识别算法，给神经网络提供每一模式类中的一些样本作为训练样本。BP网络经过学习，不仅能够识别已训练过的样本，而且能够识别未出现过的样本。利用神经网络的泛化能力，提高指纹识别算法的识别率，图像增强、提取指纹特征(BP neural network is the first mock exam to design fingerprint recognition algorithm, and it provides samples for each neural network as training samples. After learning, BP network can not only recognize the trained samples, but also recognize the samples that have not appeared. The generalization ability of neural network is used to improve the recognition rate of fingerprint recognition algorithm, image enhancement and fingerprint feature extraction)
