PDE-solution

用matlab实现了数字信号处理中的多采样转换，并依此原理进行采样转换滤波器的设计。(matlab)

说明：  很使用的一个系统辨识工具箱，其中包括许多系统辨识经典算法啊。。。希望对大家有用。(Is to use a system identification toolbox, including many system identification algorithms ah classic. . . Hope useful for all of us.)

对二维矩形阵列，进行空间谱估计！适合阵列测向的新手，建议先仔细学习基础知识。在知识积累上想进行垮越式发展，于初学者来说最重要的是能帮助你弄清楚问题根本何在。 (Of two-dimensional rectangular array, spatial spectrum estimation! Suitable for the novice to the array of measurement, it is recommended to carefully study the basic knowledge. In the accumulation of knowledge on Vietnam-style collapse would like to carry out development for the beginner to the most important thing is to help you figure out what the problem is.)

科研试验常用仪器，5209锁相放大器编程手册，可以用该手册对5209锁相放大器变成，非常实用。(Scientific research and test commonly used instruments, programming manuals 5209 lock-in amplifier, you can use the manual to the 5209 lock-in amplifier becomes very useful.)

说明：  空间谱估计的MUSIC算法的MATLAB仿真程序，请多多指教(space MUSIC spectral estimation algorithm MATLAB simulation program, the exhibitions)

数字信号处理中，几个实验的matlab原代码。(Digital signal processing, Matlab several experiments the original code.)

Electrocardiography (ECG or EKG) is the recording of the electrical activity of the heart over time via skin electrodes. This program make a EKG signal.

说明：  MATLAB三维拓扑程序，可以进行三维拓扑优化(Matlab 3D topology program)
