实现振动信号的FFT图，时域图以及两种倒谱的方法(realize the two analize way of the dao-pu for the signal)

判断下列方阵是否可对角化，是否为正定二次型（顺序主子式判断法、特征值判别法）(using MATLAB to determine if a the matrix is diagonalizable，if the real vector space is definite quadratic)

说明：  基于TOA定位算法的克劳美罗CRLB仿真程序(CRLB simulation program of TOA location algorithm)

MatlaB与C++接口若干问题解析，详细讲述了Matlab与C++在对接时的关键点(MatlaB and C++ interface to resolve a number of issues in detail about the Matlab and C++ when the key points in the butt)

这是一个关于基于VCSOA的光开关的仿真程序。仿真程序基于传输矩阵法设计的，将整个器件在轴向按折射率的不同分成很多层。计算了在外部抽运（即泵浦，加在放大器上的工作电流）呈现周期性变化时，放大器将输出一系列的光脉冲，即光开关。 ( This is a simulation package for computing the characteristics of the VCSOA when acting as an optical switch, which is designed based on TMM( transfer matrix method). The whole device is splitted into many segments in the axis direction according to different index. When the external pump is a periodic signal, the output of the VCSOA would be a pulse train, which can be used as optical switch. )
