很好的人工免疫算法，用matlab实现，寻求函数的极值(immunity )

Example - 3-D Stem Plot of an FFTFor example, fast Fourier transforms are calculated at points around the unit circle on the complex plane. So, it is interesting to visualize the plot around the unit circle. Calculating the unit circle.(Example- 3-D Stem Plot of an FFTFor example, fast Fourier transforms are calculated at points around the unit circle on the complex plane.

ODE function 求解一阶线性常微分方程(ODE function for solving first-order linear ordinary differential equations)

matlab学习手册是里面内容介绍的很详细，是学习MATLAB很好的学习资料。(matlab manual is inside the content of the study described in great detail, learning MATLAB is a very good learning materials.)

growcut algorithm is implemented for segmentation purpose

Gauss-Seidel Iteration

ASK modulation demo for TIMS software. It is the simple script to simulate ASK modulation

说明：  潮流计算，使用PQ分解法，是一种比牛顿法更优越的潮流计算法，收敛速度更快，收敛精度与牛顿法相同(power flow of P-Q)

1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(1. Produce sine wave, square wave, and the white noise signal with Matlab, and their time-domain waveform display 2. FFT transform, display each spectrum, where the sampling rate, frequency, length optional data 3. RMS to make maps of the three signals, power spectrum, as well as the number of RMS map 4. Restored by inverse Fourier transform IFFT signal and displays the time domain waveforms sinusoidal signal recovery)
