matlab 学习技巧，现在把我用的，也就是对我帮助很大的留个文件传上去，希望对大家有用，第一入门与提高(matlab learning skills, and now I use, which is a great help to me to leave a document passed up, we want to be useful, the first entry and improve)

最优波束形成的空时过程特性（包括快拍模型、空时随即过程、阵列和孔径的谱采样等）(Optimal beamforming space-time process characteristics (including the snapshot model, then space-time process, arrays and spectral sampling of the aperture, etc.))

Lax法求解一介波动方程，初始条件：c=1m/s,x=1-2时，u=2m/s.(Lax method to solve wave equation)

说明：  利用粒子群算法优化svm参数，得到高精度的svm模型(The parameters of SVM are optimized by particle swarm optimization (PSO), and the SVM model with high precision is obtained)

严格按照BP网络计算公式来设计的一个matlab程序,对BP网络进行了优化设计 优化1：设计了yyy，即在o(k)计算公式时，当网络进入平坦区时(<0.0001)学习率加大， 出来后学习率又还原 优化2：v(i,j)=v(i,j)+deltv(i,j)+a*dv(i,j) (A Matlab procedures in strict accordance with the BP network computing formula to design, the optimization design was carried out on BP network Optimization design of 1: YYY, that is O (k) in the formula, when the network into the flat area (<0.0001) learning rate increase, after learning rate and reduction Optimization of 2:v (I, J) =v (I, J)+deltv (I, J)+a*dv (I, J) )

说明：  均匀线阵情况下的，相干信号的产生，并不是入射后的信号，而是原始的相干信号，希望各位不会搞错(Uniform linear array case, the coherent signal generation, not the signal after the incident, but the original coherent signals and hope that will not be wrong)

多元分辨 MCR，Multiple resolution，matlab程序(MCR，Multiple resolution)

说明：  BP神经网络算法，BP(back propagation)神经网络是一种按照误差逆向传播算法训练的多层前馈神经网络，是应用最广泛的神经网络。(BP (back propagation) neural network is a kind of multilayer feedforward neural network which is trained according to the error back propagation algorithm. It is the most widely used neural network.)

插值算法程序，包含各种算法的例程。可以直接利用或者练习(algorithm program)

说明：  在MATLAB环境下实现量化后的PCM编码(In the MATLAB environment to achieve quantized PCM coding)
