计算3维光子晶体的能带结构，利用了平面波展开方法(calculated three-dimensional photonic crystals with the structure, using the plane wave expansion method)

river formation dynamics algorithm implementation in matlab

非负矩阵分解的最新算法的matlab实现，以及多种算法之间的对比，和在图像识别中的应用,实测可用(The latest non-negative matrix factorization algorithm matlab implementation, as well as the contrast between a variety of algorithms and image recognition applications, the measured available)

说明：  Matlab,图像识别，计算图像中物体的个数。测试图片读入图像程序图像识别计数主程序 (objectrecog)

说明：  BP算法是为了解决多层前向神经网络的权系数优化而提出来的；所以，BP算法也通常暗示着神经网络的拓扑结构是一种无反馈的多层前向网络(BP algorithm is to solve the multi-layer feedforward neural network weights optimization and put forward Therefore, BP algorithm usually implies that the topology of neural network is a multi-layer feedback-free network)

在理想信道条件下、在高斯白噪声信道条件下和在先经过瑞利衰落信道再通过AWGN信道条件下的QPSK仿真（基带输入波形及其功率谱、QPSK调制信号及其功率谱、QPSK信号星座图、误码性能等）(In an ideal channel conditions, in white Gaussian noise channel conditions and earlier through Rayleigh fading channels through QPSK simulation AWGN channel conditions (baseband input waveform and its power spectrum, QPSK modulation signal and its power spectrum, QPSK signal constellation Figure, error performance, etc.))

该程序主要是完成MSK的调制这样的一个过程。(The program mainly completes the process of modulation of MSK.)

This code is related to the course Digital Communications. It makes a simple communication system which uses AWGN and QPSK

实现emd的分解并利用svm预测，最终得到太阳能的预测结果(Realize the decomposition of EMD and use SVM prediction, and finally get the prediction result of solar energy.)
