利用matlab对暂态信号进行短时能量分析

my homework about optical power graphics.

电力系统的短路计算过程繁琐工作量大，采用计算机编程计算不但省去了繁琐的人工计算，而且精确度高。我选用matlab作为编程语言，因为Matlab对处理数组有着其它编程语言所无法比拟的优越性。此外matlab中的GUI界面直观简单，而且制作过程并不复杂。(power system short-circuit the cumbersome process of calculating workload, calculated using computer programs not only save a cumbersome manual calculation, and high precision. I use Matlab as a programming language, because Matlab have to deal with an array of other programming languages are incomparable superiority. In addition Matlab the GUI interface is very intuitive and simple, but the production process is not complicated.)

一个正弦波利用DCT，FFT变换后稀疏化，然后应用压缩感知实现压缩，并有仿真图例说明重构效果。重构算法采用线性规划和OMP算法等，是一个初学CS入门的好例子。(A sine wave using DCT, FFT transform sparse, and then apply compressed sensing to achieve compression, and a legend reconstruction simulation results. Reconstruction algorithm using linear programming and OMP algorithms, is a good example of beginner CS entry.)
