Spectrum analysis of sound signal

This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust. It takes the xy-coordinates of data points, and returns the coefficients of the equation of the ellipse: ax^2 + bxy + cy^2 + dx + ey + f = 0, i.e. it returns the vector A=(a,b,c,d,e,f). To convert this vector to the geometric parameters (This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust.

说明：  一个自动发现某年和另外一年的星期全部相同的程序。。。功能很强大 可以下载看看(An auto-discovery a year and another week of the year all the same procedures. . . Very powerful to see available for download)

主要为一个Gui演示平台，能仿真实现不同psk调制及不同状态数的STTC编码，在命令窗口输入ui_start即可进行(Gui primarily a demonstration platform, to achieve different simulation psk modulation and coding of different states of STTC in the command window can be input ui_start)

Exact Recovery of Sparsely-Used Dictionaries

实现图像的DCT高通、低通滤波器并与傅里叶变换做比较.有图可见，经DCT低通滤波后，图像变得很模糊。因为DCT是FFT取其实部，能量减少，因此图像变得很模糊，没有经FFT滤波后的效果好。 经DCT高通滤波后的图像： 经DCT高通滤波后，图像的低频部分被滤除掉，图像变黑，只有边缘的痕迹可见。 (The DCT of image high-pass, low pass filter and compared with the Fourier transform.)
