`1-magic : Recovery of Sparse Signals via Convex Programming

时频分析工具包，可用于非平稳信号处理，for matlab(This is the Time-Frequency Toolbox, a collection of about 100 M-files , developed for the analysis of non-stationary signals using time-frequency distributions. It consists in groups of signal generation files, processing files and post-processing files (including visualization tools). The toolbox contains numerous algorithms for time-frequency signal analysis, with special emphasis on quadratic energy distributions within Cohen s class and the affine class, including most recent developments based on reassignment. The Time-Frequency Toolbox has been developed by Francois Auger, Olivier Lemoine, Paulo Gonlv and Patrick Flandrin during the years 1995-1996. Later, modifications for Matlab 5 were made available.)

说明：  方便矩阵分解运用，可以去掉矩阵相关性，方便gps模糊度快速解算(Facilitate the use of matrix decomposition, correlation matrix can be removed to facilitate rapid ambiguity gps calculation)

说明：  卡尔曼滤波源代码，含有噪声设置，特别适合初学者(Kalman filter source code, with noise, especially for beginners)

说明：  谱减法的测试程序，能够测试谱减法的去噪能力以及相关信息。(Spectral subtraction of test procedures to test spectral subtraction denoising and related information)
