Matlab中所有的内部函数，学习后能够全览matlab中的函数。(Matlab, all internal functions, learning later to be fully in relation to the function of matlab.)

该文件是PQ分解法，可以更有效地解决IEEE30节点系统的潮流，希望可以给广大朋友一定的帮助。(The file is PQ decomposition, can more effectively address the trend IEEE30 bus system, hoping to be helpful to the general friend.)

Kerr的经典著作，短波电波电波传播理论。(Kerr, theory of short wave radio wave propagation .)

matlab 2014a 破解文件，亲测可用。软件太大了，可在官网自行下载。(Matlab 2014 a crack file, close test available. The software is too big, can be in official website to download. )

说明：  对400幅灰度图像用分块PCA的方法进行压缩，进行通信时只用传输主元和特征向量。其中，pcaxiefangcha.m用于图像压缩，imresume.m用于图像恢复和部分图像的显示，chaweight.m用于绘制特征值比重-主元个数关系图，crdraw.m用于绘制压缩比-主元个数关系图，psnrdraw.m用于绘制总误差PSNR-主元个数关系图，psnrlocation.m用于绘制单幅图像误差PSNR分布图。(On the 400 block with a gray image compression method of PCA, to communicate only the main elements and characteristics of transfer vectors. Which, pcaxiefangcha.m for image compression, imresume.m parts of the image for image restoration and display, chaweight.m characteristic value for the draw weight- the main element number diagram, crdraw.m used to draw the compression ratio- the primary element number diagram, psnrdraw.m used to draw the total number of errors PSNR-principal component diagram, psnrlocation.m PSNR used to draw a single image error distribution.)

很好的MATLAB仿真可以包括通信所有方面所以可以看看(good matlab)

本程序可以正常下载，运行。线性分组码定义，对于长度为n的二进制分组码，可以表示成（n，k），通常用于前向纠错。在分组码中，监督位加到信息位之后，形成新码，在编码中，k个信息位，被编为n位长度，（n-k）个监督码的作用是实现检错和纠错。(linear block code)

给于MATLAB 环境下的非线性滤波器。此设计中用到了，混合网络建模。B样条网络和对角递归神经元网络。(In the MATLAB environment to the non-linear filter. This design used a mixed network modeling. B-spline network and on the diagonal recurrent neural network.)

Hu矩的计算，通过Hu矩计算可以实现图像的旋转、平移的不变特性(Hu Moment, can be achieved by Hu Moment of image rotation, translation invariant features)
