Sparse Reconstruction by Separable Approximation

能够模拟光纤光栅，对于我们的实验研究有很大的帮助，是我们能够了解它大概的趋势买并且有助于实验的制作(Able to simulate fiber grating, for our experimental study of great help, we are able to understand it' s probably a tendency to buy and help make the experiment)

This program shows how convolution works, going through all the steps of exactly what gets added up and multiplied with what. It also explains from the ground-up how to do for-loops in Matlab. (By the way, if you want to see an example of how to "vectorise" code to avoid for-loops altogether, look at the bkprop.m program in my

基于PWM变换技术的电力电子变压器，主要介绍了电力电子变压器及其在MATLAB环境下的仿真。(Research PWM conversion technology based on power electronic transformer of MATLAB.)

MATLAB实现对该系统的潮流计算。需要MATLAB语言编制程序形成节点导纳矩阵、形成雅克比矩阵、用高斯消去法解修正方程式，并编写输出程序用以输出节点导纳矩阵、节点电压（包括电压的相角和幅值）、以及各支路的首端功率、末端功率和功率损耗(MATLAB implementation of the system flow calculation. MATLAB programming language requires the formation of the node admittance matrix, Jacobian matrix formed by modified Gaussian elimination method for solving equations, and write out procedures for the admittance matrix of the output node, the node voltage (including the voltage phase angle and amplitude), and the first end of each branch of power, end power and power loss)

An electrocardiogram (ECG) records the electrical activity of the heart. The heart produces tiny electrical impulses which spread through the heart muscle to make the heart contract. These impulses can be detected by the ECG machine. Electronic fetal ECG monitoring is a technique of obtaining important information about the condition of the fetus during pregnancy, by measuring the electrical signals generated by the fetal heart as measured multi-channel electrodes placed on the mother’s body surface. Fetal ECG (FECG) monitoring enables accurate measurement of fetal cardiac performance including transient or permanent abnormalities of rhythm. During labor and delivery, the heartbeat of the baby is monitored in order to make sure that enough blood flow and oxygen are getting through to the unborn fetus.
