飞行器航迹曲线,三维空间仿真,包括直行,爬升,转弯,俯冲等等运动姿态(Aircraft flight path curves, three-dimensional simulation, including straight, climbing, turning, diving, etc. sports gesture)

自适应建模与其模型的逆估计，MATLAB编写，加高斯白噪声(Adaptive Modeling and its inverse model estimates, MATLAB prepared, add white Gaussian noise)

this is a codeto detect voice or unvoice specch

emprical model decomposition经验模态分解，可以对随机信号自动分解成本征模函数，matlab实现代码(emprical model decomposition)

实现高通和低通滤波，主要是先进行傅里叶变换，然后对频谱图滤波后再逆变换得到滤波之后的图片(High-pass and low pass filter, mainly the first Fourier transform, frequency spectrum and then inverse transform filter and filtered image)

随机数生成的matlab程序，可作为数值分析等的学习工具。(Matlab program, the random number generator can be used as a learning tool of numerical analysis .)

说明：  文档中有3个程序。h.264灰度处理程序，DCT变换程序，DCT系数量化程序。(There are three programs in the document. The h.264 gray handler, and DCT transform process, the DCT coefficient quantization process.)

求解Lambert问题。 输入：轨道上两个点的位矢R1、R2，以及从R1到R2所用的时间t(缺点是脉冲太大)。 输出：质点在R1端点的速度V1，质点在R2端点的速度V2. 此函数用于：在给定轨道上两个点的位矢R1、R2，以及从R1到R2所用的时间t。求解V1、V2。再调用前面的函数就可以确定轨道根数，及任意时刻质点的状态。(To solve the Lambert problem. Input: track two-point position vector R1, R2, and R1 to R2 used in the time t (The disadvantage is that the pulse is too large). Output: particle R1 endpoint speed V1, the particle in the R2 endpoint speed V2. This function is used: two points in a given orbit position vector R1, R2, and from R1 to R2 with the time t. Solve the V1 and V2. And then call the previous function can determine the orbital elements, and any moment of the particle' s state.)

这个压缩文件主要是关于一些图像分割的实例，值得学习。(This compressed file is about image segmentation instance, it is worth learning.)
