说明：  无线传感器网络LEACH算法的matlab模型(Wireless sensor networks LEACH algorithm matlab model)

Numerical Analysis Using MATLAB and Excel - Steven T. Karris

在以往研究的基础上,实现火灾下 建筑空间环境和疏散行为的仿真模拟(On the basis of the above research, the simulation to realize the construction of the space environment under fire and evacuation behavior)

低频信号先进行放大，再调制解调，设计发射(Low-frequency signal is first amplified, and then modulation and demodulation, the transmitter )

its about how to calculate the distance by matlab

说明：  主要功能： 1.完成传感器对目标状态的kalman滤波估计； 2.对传感器的状态估计进行SCC和CI融合； 3.画出位置及速度的估计和融合误差曲线、真实航迹及融合后航迹、K=1时刻的协方差椭圆(Main functions: 1. The Kalman filter estimation of the target state is completed; 2. The state estimation of sensors is fused by SCC and CI; 3. Draw the error curve of position and velocity estimation and fusion, real track and fusion track, covariance ellipse at k = 1)

说明：  关于信号输入均匀量化器的信号幅度，用MATLAB实现量化过程(Uniform quantizer on the input signal amplitude, using MATLAB to quantify the process of achieving)

这个是图像轮廓提取的matlab程序，而且提取完后还能把所有轮廓用不同颜色分开存放到轮廓矩阵cell中，方便用户对感兴趣的轮廓进行操作--张璐奉献(This is the matlab image contour extraction process, but also exhausted all the contours extracted with different colors kept separate from the profile cell in the matrix, user-friendly to operate the contours of interest- Zhang Lu dedication)

说明：  永磁同步电机矢量控制仿真，Matlab版本至少为R2013a，控制器及模型均为离散形式，附带有离散形式的DOB和Enhanced DOB，实现谐波注入，降低转矩脉动(FOC control of PMSM, servo systems, disturbance observer, torque ripple)

说明：  用matlab实现的曼彻斯特编码。50 占空比（可调）。绘制时域波形和频域功率谱密度。结果跟北邮的郭文斌的通信原理课件上的形状一模一样。(Manchester encoding with a matlab implementation. 50 duty cycle (adjustable). Draw time-domain waveform and frequency domain power spectral density. The results with the Beijing University of Posts and Telecommunications of the GUO of communication theory on the shape of the same courseware.)
