SituationDevelopment

这个程序用来模拟windows计算器,为薜定宇老师<<科学运算语言MATLAB5.3程序设计与应用>>的习题而做(It is suitable for beginners to master matlab deep into the second developed a good teaching examples of great reference value)

modulation and demodulation 16-QAM

领域：数字信号处理。使用MATLAB实现频率采样型滤波器。含一阶与二阶谐振柜的实现、频率采样信号的恢复的MATLAB文件，都很有用。(Areas: digital signal processing. Use MATLAB to achieve frequency sampling filter. With first and second-order resonance cabinet realization, MATLAB file recovery frequency of the sampled signal, very useful.)

data mining using matlab

说明：  匈牙利算法源码，封装为函数，可以直接调用，可以运行(Hungarian algorithm source code, encapsulated as a function, can be called directly, can be run)
