一个50行的Matlab有限元程序（二维非线性问题），执行fem2d_nonlinear.m即可。(A 50-line Matlab finite element program (two-dimensional nonlinear problems), the Executive fem2d_nonlinear.m can.)

说明：  matlab数学公式的汇总，可以解决编程时数学公式的问题(matlab summary of mathematical formulas, mathematical formula to solve programming problems)

用于函数逼近的BP算法程序，可在Matlab中调试运行，绝对可行(For function approximation of the BP algorithm procedure can be run in debug Matlab is absolutely feasible)

Given 2 subscripts, j & k, KronD will return 1 if j == k and 0 if j != k. A very simple function with only a single if-else statement. Saves a bit of typing when the Kronecker Delta is needed.

利用Matlab生成C/A码的基带/中频信号和P码的基带/中频信号，也就是生成一个完整调制在的L1载波上的信号。 (Using Matlab to generate the C/A code baseband/IF signal and the P code baseband/IF signal, is to generate a complete modulation of the signal in the L1 carrier.)

一些基本的語法練習，可以拿來實際應用，包含了註解與程式(Some basic grammar exercises, can be used to practical applications, including annotations and programs)

日本人做的一个雷达系统仿真的matlab的toolbox，里面包含了绝大多数雷达信号的模拟，可以用与仿真，如果 要用到硬件设计则不太好使(Japanese do a radar system simulation Matlab toolbox. it contains the majority of the radar signal simulation, and simulation can be used, if we had to use the hardware design is not good enough so)

最佳权向量自适应迭代更新MSE对比波形，内有详细说明，供大家参考。(optimal weight vector adaptive waveform update MSE contrast, with detailed notes for reference.)

Firmware replacement code.

说明：  基于遗传算法，进而优化惩罚因子，核函数参数的的支持向量机进行分类(GA SVM classification)
