principal--stress

this program performs pulse position modulation of two sequences: the sine wave and the triangular wave

说明：  用Matlab实现声波信号的傅立叶变换。可直接倒入音频，生成图像。(Acoustic signals using Matlab Fourier transform to achieve. Directly into the audio and generate the image.)

利用Capon, MUSIC进行窄带信号空域信号方向估计。比较分辨率性能。观察阵元数、信噪比、快拍数对估计器性能的影响。 (Using Capon, MUSIC for narrowband signal airspace signal direction estimates. Comparative resolution performance. Observe the number of array elements, signal to noise ratio, the number of snapshots on the estimator performance.)

说明：  例题运行步骤:在Matlab命令窗口将本章目录置于当前目录；在Matlab命令窗口的当前目录中打开本章目录中的M文件Exam.m；在Exam.m文件中，将待运行例题前的注释符号“ ”去掉，并保留其他例题前的注释符号“ ”；在命令窗口键入：Exam 并回车即可运行该例题。(Example run these steps: In the Matlab command window will be placed in this chapter directory the current directory in the Matlab command window to open the current directory in the directory of this chapter M files Exam.m in Exam.m file, will be run before the note symbol example &quot &quot removed and reserved comment symbol in front of the other examples, &quot &quot in the command window, type: Exam and press Enter to run the examples.)

code鱼群算法在函数优化中的应用,包括一元函数二元函数,动态图像(fish swarm algorithm code in function optimization applications, including one yuan function binary function, dynamic image)

高斯函數方程式案例，主要是以matlab軟件來運算標準題型。(Gaussian equation case, mainly matlab software to compute the standard questions.)

这是一个OFDM的仿真，里面的untitled.A为主函数，最后出现误码率ber的仿真图(This is an OFDM simulation, the main function inside untitled.A, last seen ber BER simulation map)

前面搞错了,把五个文件一起打包上传了,现在一个一个传 预加重声波在噪声信道内传输 模拟程序 程序头上有详细的注释和使用说明(Made a mistake in front of the pack with five file upload, and now a mass of a pre-emphasis acoustic noise within the transmission channel simulation program procedures detailed head notes and use)

在matlabzhong 运用5种不同的梯度增强法对图像进行图像锐化(For image sharpening use five different gradient Enhancement Act)

说明：  基于蒙特卡洛仿真的电动私家车负荷充电预测，考虑了三种不同的充电情景(Prediction of Private Car Load Charging Based on Monte Carlo Simulation)
