极坐标系下的画图及其转换公式，特殊作图需要用到(Polar coordinates of the drawing and the conversion formula, need to use special drawing)

MATLAB neural network backprop code This code implements the basic backpropagation of error learning algorithm. The network has tanh hidden neurons and a linear output neuron. adjust the learning rate with the slider

nii格式文件的读取，输入指令var_nii=nii_load( **.nii ) (nii read the file format, enter the command var_nii = nii_load ( **.nii ) )

关于支持向量的简单分类和多分类与优化，还有不变矩的编程(Support vector classification of simple and multiple classification and optimization, there are moment invariants programming)

很好的MATLAB书籍，推荐！新手入门的好资料。(MATLAB good books, recommend! Good data entry of the green hand. )

无标度网络结构相对简单,实现算法与可视化并不困难。与其它语言相比,Matlab 语言具有丰富的数学 函数库,能够写出简约的源代码。对于非计算机专业的大学生来说,以此为基础,能够快速进入复杂网络前沿 研究课题,对其数学建模能力和科研能力的培养极为有益。(Scale-free network structure is relatively simple algorithm is not difficult and visualization. Compared with other languages, Matlab language with a rich library of mathematical functions, can be simple to write the source code. For non-computer science students is as a basis to quickly enter the complex network of cutting-edge research topics, their mathematical modeling and scientific research is extremely useful ability.)

说明：  内含OFDM 峰均比的仿真程序，选择性映射slm和部分序列pts(OFDM PAPR includes simulation program, selective mapping and partial sequence pts slm)

用matlab实现2psk比较详细，从二进制码到成型滤波到最终2psk信号都能成功实现(Using matlab to achieve 2psk in more detail, the binary code to the final 2psk signal shaping filter can be successfully achieved)

solution of numerical integration with newton method

说明：  分析了LTE系统频率偏移，定时误差，信道估计问题等，并对广义Rake接收机和CPEDS接收机的性能做了比较。(Analysis of the LTE system frequency offset, timing error, channel estimation problems, and generalized Rake receiver performance receiver and CPEDS were compared.)
