MATLAB掌握和精通经典教程Grasp and master the classic MATLAB Tutorial(MATLAB grasp and master the classic tutorial Grasp and master the classic MATLAB Tutorial)

这是一个用MATLAB编的模拟一个小球的下落过程 ,很不错,希望和大家分享.(This is an addendum to the MATLAB simulation of a small ball on the whereabouts of course, very good, and he hopes to share with you.)

There is a simulation of Orthogonal Frequency Division Multiplexing (OFDM) in by multipath fading channels. (There is a simulation of Orthogonal Frequency Division Multiplexing (OFDM) in by multipath fading channels.)

这是一个小波去噪的程序，除了实现了最经典的图像去噪算法外，还使用了最新的带有方向性的小波，去噪效果非常好(This is a wavelet denoising procedure, in addition to realize the most classical image denoising algorithms, but also uses the latest with a directional wavelet, denoising effect is very good)

用于黑启动求解频率变化值的PQ潮流分解，输出由每次迭代后各参数的变化量。(PQ trend for black start solving the frequency change value decomposition, the output from each iteration, each parameter change.)

详细的卷积编码与维特比译码算法。产生随机信号，对信号进行卷积编码，然后经过数值转换、格雷编码，QPSK调制，进入加噪信道，之后进行QPSK解调，格雷解码， 数制转换、 维特比译码得到接收端的信号。(Detailed convolutional coding and Viterbi decoding algorithm. Random signal, the signal convolution coding, and then through numeric conversion, Gray coding, QPSK modulation, plus noise into the channel, followed by QPSK demodulation, decoding Gray, number system conversion, Viterbi decoding to get the receiving end of the signal.)

Elman神经网络建立建筑物电力负荷预测模型中遇到的几个关键问题有，数据归一化处理、输入输出样本的选取、隐含层节点数的确定；分别建立Elman神经网络模型，并利用某栋建筑物实际历史电力负载数据进行预测，分析比较与实际数据值的预测精度，得出了一个有效的数据预测模型。(Several key problems encountered in building power load forecasting model based on Elman neural network are data normalization, selection of input and output samples, and determination of the number of hidden layer nodes. Elman neural network models are established respectively, and the actual historical power load data of a building are used for forecasting. Effective data prediction model.)
