MATLAB经典案例系列的MATLAB与Excel交互的案例(EXCHANE MATLAB with EXCEL )

本文采用的是先对脉搏波进行经验模态分解，产生一组内在的模函数，每一种模态对应一种物理状态，之后使用ＨＴ得出瞬时的频率和振幅，进而得到边际谱(In this paper, is the first of the pulse wave empirical mode decomposition, resulting in a set of intrinsic mode function, each mode corresponds to a physical state, followed by the use of HT derived instantaneous frequency and amplitude, and thus to be marginal spectrum)

新手学习MATLAB画图很好的例子，程序直接复制到MATLAB中就可以运行。(MATLAB drawing newcomers to learn a good example, be copied directly into MATLAB programs can run.)

BFT,正交傅里叶变换，用于检测线性调频斜率的方法。仿真与论文结果一致。(BFT, orthogonal Fourier transform for detecting the slope of the linear frequency modulation method. Simulation results are consistent with the thesis.)

关于弹簧连接耦合摆的计算模拟。求出系统的两个简正模和一般振动解。并做出摆的位移曲线，分析振幅调制现象。(Connect coupling on spring pendulum simulation. Obtained system of two normal vibration mode and the general solution. And make a pendulum displacement curve, analysis of the phenomenon of amplitude modulation.)

Finite Volume Method 流体仿真代码 利用TDMA算法计算二维矩阵 从而计算出二位场内各点的性质 可以通过修改步长和网格大小实现算法研究(A computational fluid dynamics code for determine the property of a two-dimensional plate by using Finite Volume Method. Grid size and time step are free to change in this code.)
