汉明码编码仿真程序，在Matlab环境下仿真，适用于初学者。(Hamming code encoding simulation program, in the Matlab simulation environment for beginners.)

高阶谱分析,用于检测两个信号的延时情况,应用方面非常广泛，适用于阵列信号处理、雷达信号处理等.包含了TDEL文件和tdeb.m(Higher-order spectral analysis for the detection of two signals delay the case, the application is very widely used for array signal processing, radar signal processing. Contains TDEL files and tdeb.m)

说明：  主要介绍16QAM调制，及其算法的应用。(This paper mainly introduces 16QAM modulation.)

传递矩阵法计算转子固有频率，大转子，prhol传递矩阵法(Transfer matrix method the rotor natural frequency, the greater trochanter, prhol transfer matrix method)

说明：  天线和电磁波计算的书籍，环境为MATLAB.(Antennas and electromagnetic wave calculation of books on the environment, MATLAB.)

地震反应谱计算方法，可以对于地震进行预测监控，方便及时进行相关措施减少人员伤亡和财产损失。(The calculation method of seismic response spectrum, earthquake prediction can be convenient for monitoring, timely measures to reduce casualties and property losses.)

说明：  本程序运行需一个小时左右。优化准则是旁瓣电平最小。取栅格间距为lemda/2,阵元间距为栅格间距的整数倍。放阵元的位置放1，否则放0(This program should be running an hour or so. Rule of optimization is side-lobe level minimum. Take grid spacing for lemda/2, spacing for grid spacing array (integer times. Put the position of the array (put 1, otherwise put 0 )

时程积分法解非线性动力方程时程,其中有迭代格式的牛顿拉普孙(newmark algorithm for nonlinear dynamic eqaution——newton rapthon is included)
