utility file to plot two functions simultaneously

复数噪声信号的产生，包括高斯白噪声和色噪声（滤波器可定义）(plural noise signal produced, including white Gaussian noise and color noise (Filter definable))

图像拼接Matlab程序，基于块匹配的全景图像拼接(Image mosaic Matlab program, based on block matching panoramic image stitching)

说明：  针对“BreastCancer”数据集，作为对比，第一次对特征集直接进行SVM分类，第二次使用粒子群算法进行特征选择后再进行SVM分类。并且对比和分析了两次分类的结果。(For "BreastCancer" data set, as a comparison, the first time the feature set is directly classified by SVM, and the second time the feature set is selected by particle swarm optimization before SVM classification. The results of the two classifications are compared and analyzed.)

很好的matlab参考书，唯一的缺点是全英文，不过写得很详细(Matlab very good reference book, the only drawback is that the whole English, but very detailed)

DQPSk调制过程 解调过程 系统误码率 matlab程序(Modulation process DQPSk BER demodulation matlab process procedures)

matlab的QAM调制和解调，很不错的！()

calculate the DFT Coeff index array

说明：  灰色预测模型的matlab算法实现，可以进行较为长期的预测(use matlab to solve gm problem)

本代码主要运用MATLAB的simulink的模块构建了一个OFDM的基本链路，并研究了AWGN信道在不同SNR下产生的误码率(BER).(This code mainly uses the MATLAB module of Simulink to build a basic link of OFDM, and studies the error rate (BER) of AWGN channel under different SNR)
