基于FDTD算法，用MATLAB实现了波导色散特性的仿真研究(Based on the FDTD algorithm, implemented using MATLAB simulation of waveguide dispersion characteristics)

This is PCA source. please contact me if you have some question.

可实现函数的产生，基本运算，时域频域分析(Generation function, basic operations, time domain frequency domain analysis)

基于阈值分割心音信号，阈值可根据信号调整，程序给出心音分割的起止位置。(Threshold-based segmentation of heart sound signals, the threshold can be adjusted according to the signal, the program gives the starting and ending positions of heart sounds segmentation.)

sml MUSIC DOA simulation with matlab

编写的数值分析power方法matlab程序(numerical method for power method )

说明：   1、 设有一个起始地址为FRIST + 1的数据块，存放在内部RAM， 数据块长度在FRIST单元且不为0，要求统计该数据块中值为0的个数， 并将它们分别存放在FRIST - 1单元单元，试编写出相应程序。(1, with a starting address FRIST+ 1 block of data stored in internal RAM, the data block length of 0 in the FRIST unit and not to require statistical data block 0 in the number of them were stored In FRIST- 1 unit cell, try to write the corresponding program.)

Default constructor, for use by subclasses.
