qsort

基于快速傅里叶变换的GUI设计，能对多个输入序列进行FFT分析，并在画面上显示出输入信号，经过FFT处理，经过IFFT处理的信号波形(GUI design based on the fast Fourier transform, FFT analysis of a plurality of input sequences, and displayed on the screen of the input signal after FFT processing, the signal waveform after the IFFT processing)

说明：  这是一个信赖域方法的程序，简单实用，对初学者非常有用(This is a trust region method procedures, simple, practical, very useful for beginners. )

matlab的音频指纹提取, 小波包, 需要用到voicbox工具箱(matlab audio fingerprint extraction, wavelet packet, need to use voicbox Toolbox)

数学形态学对信号进行去噪，效果较好，信号扰动特征得到很好保留(Morphology of the signal de-noising effect is good, the signal disturbance characteristics are well retained)

高级优化算法 粒子群优化算法(求解无约束优化问题) PSO(基本粒子群算法)(Advanced Optimization Algorithm Particle swarm optimization (unconstrained problem) PSO (Particle Swarm Optimization))

Dear Sir this file describe and analyse the wind turbine so it is a new approach model

matlab实现log算子，进行图像边缘的提取(matlab realize log operator to extract image edge)

An example of the German enigma encryption technology COOL

小波包分解重构后，求节点能量，matlab中运行很好(After the wavelet packet decomposition and reconstruction, the node energy is calculated, which runs well in matlab.)

這是我用scilab寫的高私後向消去與樞軸的程式語法，和高絲後向消去法的差異可見(This is what I write with scilab after the high-private programs to eliminate and pivot grammar, and high-thread after the elimination of the difference can be seen)
