这是一个研究生课程的matlab课件，方便大家学习matlab，希望能给大家带来帮助(This is a post-graduate courses matlab courseware to facilitate learning matlab, hope everyone can help)

分别用三种不同的差分近似公式（前向差分、后项差分和中心差分）来技术函数的近似值(Respectively with three different difference approximation formula (forward difference, backward difference and central difference) approximation to the technical function)

基于Hilbert_Huang变换的基音周期提取方法(basic-speech drawing based on Hilbert_Huang)

This code implements the direct kinematics of a 3 revolute robot. It also includes a simple graphic model of this operation.

根据任何先验知识未知的多传感器检测同一目标的情形，根据支持度矩阵，获得各个传感器在不同时刻的一致性度量。(Based on any a priori knowledge of unknown multi-sensor target the same situation, according to the support matrix, each sensor at different times to obtain the consistency of measurement.)

多帧图像数据拟合，可以对多幅图片数据进行数据拟合。(Fitting multi-frame image data, image data can be multiple data fitting.)

利用matlab离线处理数据实现经验模式分解（EMD）算法(Offline data processing using matlab to achieve empirical mode decomposition (EMD) algorithm)

可以完成DMC动态矩阵预测控制的部分内容，非常有用。(DMC Dynamic Matrix Control part can be completed, is very useful.)
