OFDM Transmitter and Receiver code with mapping , channel coding ,channel estimation and apply fading

这是用matlab工具箱解决热传导微分方程的一个实例，这里用正六边形、圆形、矩形的三个算例，同时画出来了图像表示温度分布(you can use it to solve the equation and make a picture with matlab,it s easy and straight)

简单的 knn 文本算法 ，用于中文文本分类，比较方便的方法！(Simple text knn algorithm for Chinese text classification, more convenient way!)

matlab code for modelling low pass filters

这个程序是用来计算盘基片的厚度和折射分布的程序.(this file is used to calculate the thickness and the refractive index of thse sample, and these two parameter distribution ca nbe obtained.)

对称阵子的方向系数D随臂电长度的变化图，该图为二维的。(Stream of the direction of symmetry coefficient D changes with the electrical length of arm map, the picture shows the two-dimensional.)

EMD algorithm..used in speech processing, breaks trhe signal upto fundamental levels

在matlab编译环境下，下实现迪杰斯特拉算法。 程序鲁棒，速度较快。(the implementation of Dijstla algorithm)

说明：  matlab编的标签页，很容很强大~~~~~(matlab code of the tab page, it is very strong capacity ~~~~~)
