Ritz法解决-u +u=x 0<x<1，u(0)=0,u(1)=0的有限元边值问题。精确解为u(x)=1/(exp(1)-1/exp(1))*exp(-x)+1/(1/exp(1)-exp(1))*exp(x)+x，基函数为g(i)=sin(i*pi*x)(This matlab code is used to solve the boundary value problem of the differential equation: -u +u=x 0<x<1，u(0)=0,u(1)=0, where the accurate solution is : u(x)=1/(exp(1)-1/exp(1))*exp(-x)+1/(1/exp(1)-exp(1))*exp(x)+x)

详细介绍了matlab中simulink的使用方法等(Described in detail the use matlab simulink)

说明：  利用matlab进行随机信号处理，从宽带信号中分离出单频信号，有一定得参考价值(ADSP signal processing！)

用matlab求响应曲线包络线的程序，是用来绘制lamb波在复合材料板中的传播响应曲线的。(Use matlab for response curve of envelope，Is used to draw the lamb wave propagation in composite material plate response curve。)

说明：  离网逆变器带非线性负载，能发出指令电压谐波，用于实验补偿电压谐波，供参考。(Off-grid inverter with nonlinear load, can send out voltage harmonic instruction, used for experimental compensation voltage harmonic, for reference.)

无线传感器网络QoS路由BERR算法，matlab程序(QoS routing BERR algorithm for wireless sensor networks )

This is an implementation of the algorithm described in our paper [1]. The input is any map generated by saliency detection algorithms like Itti-Koch [2] or GBVS [3]. The algorithm outputs a binary mask without requiring a threshold for the saliency map. More details about it are described in our paper.
