green project in matlab

说明：  昨天刚刚写好的dsb-sc信号生成与解调程序，用离散（dsp）的方法生成DSB信号，载波频率为150khz,音频是500hz和2000hz的混合音，加入SNR=1DB的噪声，用正交解调实现解调，画出解调前后的频谱图，欢迎共同学习，进步。(yesterday just finished the dsb- sc signal generation and demodulation process, discrete (dsp), the signal generated DSB, the carrier frequency of 150kHz, audio is 500Hz and 2000hz mixed audition to join SNR = 1DB of noise, with quadrature demodulator to achieve demodulation, paint around the demodulation spectrum welcome to learn together and progress.)

用matlab实现了3次样条，拉格朗日。辛普生、梯形等数值分析里面的重要内容。代码可用性强，可以直接调用。另外还有实验报告，非常详细的报告。(A 3 times with matlab spline, Lagrange. Simpson, trapezoidal numerical analysis and other important content inside. Code availability strong, can be called directly. There is also experimental report, very detailed report.)

dijkstra算法 用于计算TSP旅行商问题， (Tuihuo suanfa)

轴承故障模拟仿真程序，包括内圈、外圈及滚动体故障的matlab程序(Bearing Fault simulation procedures, including the inner and outer rings and rolling fault matlab program)

一款很好用的MATLAB程序,运行会可以从清楚 的图形中看到结果(A good use of MATLAB procedures, will run from clear to see the results of graphics)

该文件是包含通信系统ARMA方法的诸多程序，是信号处理的主要部分，希望对大家有帮助。(The document is ARMA methods of communication systems include a number of procedures is a major part of signal processing, and they hope to help everyone.)

可以实现粒子群算法与盲源分离算法的结合，比较方便。源信号可以随便替换(PSO algorithm can be achieved with the combination of blind source separation algorithms, more convenient. Source signal can be easily replaced)

matlab进行仿真，希望对大家的学习和工作有所帮助(matlab simulation, in the hope that the U.S. be helpful to study and work)

该文件中包含信息熵和图像熵的计算 源程序，均为m文件形式 (The calculation of the image information entropy)
