用有限元法求解三角形形区域上的Possion方程(using the finite element method triangle-shaped region of Possion equation)

Local Triplet Pattern

基于MATLAB的数字水印程序，我不懂大家下着看吧(MATLAB-based digital watermarking process, I do not know how we look forward to the next)

详细Matlab函数查询手册（官方英文）(Matlab Function )

信源为数字信号信道信噪比为10dB的直扩通信系统仿真实验-LDPC译码仿真源代码(Source to a digital signal channel 10dB SNR DSSS communication system simulation simulation-LDPC code decoding)

本课题主要是在Simulink环境中对双闭环直流调速系统进行仿真设计，具体内容有：对电流调节器和转速调节器进行校正设计；对电流环和转速环进行时域和频域分析；对调速系统进行跟随性和抗扰性分析。(This issue is mainly in the Simulink environment on the Double Loop DC Speed Control System simulation with the specific content: The current regulator and speed regulator for correct design of the current loop and speed loop time domain and frequency domain analysis swap speed system and immunity following analysis.)

标幺化模型下的感应电机转矩——转速特征曲线的验证，标幺化的转速范围为[0-2]，如仿真步长不为1/8e3，仿真前请调整(Under the per-unit model induction motor torque- speed characteristic curve verification, per unit of speed range [0-2], such as simulation step 1/8e3 simulation before adjustment)

The Program helps to remove numbers at the beginning of a Matlab script. It is very useful when one has copied a code from a text into Matlab environment and eager to tun it immediately.

主要是将模糊聚类分选算法应用于雷达信号分选中，已达到更好的分选效果(The fuzzy clustering algorithm is applied to radar signal sorting, which has achieved a better sorting effect.)

说明：  matlab统计分析案例，经典教材，值得好好学习，对数模很有帮助(Matlab statistics, which is quite worth reading and is beneficial to mathmatical learning.)
