用matlab写的时频分析工具箱，对数学建模，信号处理有很大的帮助(Using matlab toolbox written in time-frequency analysis, mathematical modeling, signal processing, very helpful)

助推滑翔飞行器轨迹仿真程序，可实现跳跃滑翔和平衡滑翔轨迹的仿真，采用伪谱法或直接打靶法可实现轨迹优化(glide trajectory)

傅里叶变换功能的实现，虽然是非常见得的频率成分，但是还是实现了基本的傅里叶变换功能，并不是matlab自带的fft函数。实现了频谱分析可视化。(Fourier transform function, although it is very frequency components appear, but still achieve the basic function of the Fourier transform, comes not matlab fft function. Achieve a spectral analysis visualization.)

说明：  MATLAB实用程序百例，涉及到很多方面的MATLAB源程序，一定有你想要的。(MATLAB utility 100 cases, involving many aspects of the MATLAB source code, there must be what you want.)

用matlab求二维凸包，并求出二维凸包的面积(Using matlab to calculate the two-dimensional convex hull, and find the two-dimensional convex hull area)

A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies. DCTs are important to numerous applications in science and engineering, lossy compression of audio (e.g. MP3) and images (e.g. JPEG) (where small high-frequency components can be discarded), to spectral methods for the numerical solution of partial differential equations. The use of cosine rather than sine functions is critical for compression, since it turns out (as described below) that fewer cosine functions are needed to approximate a typical signal, whereas for differential equations the cosines express a particular choice of boundary conditions.
