说明：  基于小波变换的二进制相移键控系统，BPSK信号检测 (Wavelet-based binary phase shift keying system)

一些数学建模用到的函数，代码，初学者可以试着编译看输出结果(some function to make mathmatic model)

使用Crank-Nicolson隐式差分格式求解传热方程；第一类边界条件；初始条件已知。(Using the Crank-Nicolson implicit difference scheme for solving heat transfer equation the first boundary condition initial conditions are known.)

用于计算混沌分析中的柯尔莫哥洛夫熵的STB算法(for compute the Kolmogorov entropy)

OFDM的QPSK调制与解调,有说明，有需要的朋友可以看看(OFDM QPSK modulation and demodulation, a note, a friend in need can look)

Adaptive Composite Differential Evolution Algorithm 自适应复合差分进化算法(Differential Evolution with Composite Trial Vector Generation Strategies and Control Parameters)

本程序是基于支持向量机的图像分割问题。通过支持向量机对图片的采样点进行训练，然后对整张图片进行预测。可以将图片分为前景与背景两个部分。(This procedure is based on the support vector machine image segmentation problem. Through the support vector machine to the picture of the sampling point for training, and then the whole picture to predict. Images can be divided into two parts: foreground and background. )
