说明：  可以实现一种也用m序列与walsh序列复合而成的复合序列的生成。(Can also realize an m sequence and walsh composite sequence from the generation of the composite sequence.)

说明：  图像量化方式，模糊C均值 可用于图像分类(Fcm for image Quntation)

运动方程中的速度向量和加速度向量用位移的某种组合来表示，将微分方程组的求解问题转化为代数方程组的求解问题，并在时间区间内求得每个微小时间区间的递推公式，进而求得整个时程的反应。 中心差分法是一种显示的积分法，它基于用有限差分代替位移对时间的求导（即速度和加速度）。(Velocity vectors and acceleration vectors in motion equations are expressed by a combination of displacements. The problem of solving differential equations is transformed into the problem of solving algebraic equations. The recurrence formulas of each small time interval are obtained in the time interval, and then the response of the whole time interval is obtained. The central difference method is a display integration method, which is based on the finite difference method instead of the displacement derivative of time (i.e. velocity and acceleration).)

一种用于非线性降维的流形学习算法，主要是先考虑用每一点处的局部切空间表示该点处的几何特征，然后都局部切空间进行排列(A manifold learning algorithm for nonlinear dimension reduction, mainly consider to use every bit of the local tangent space representation of geometric feature at that point, then the local tangent space alignment )

说明：  信号采样 欠采样 过采样 临界采样 信号频谱 采样频率(Signal sampling undersampling oversampling critical sampling signal spectrum sampling frequency)

汽车悬架仿真建模，比较好，适合初学者学习(Simulation modeling of vehicle suspension, the better for beginners to learn)

自编的图片旋转的函数，不是matlab原有的函数，而是根据原理自己写的(self picture rotation function, Matlab is not the original function, but on the basis of principles to write)
