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)

个人硕士论文的关于数字接收机调制解调方面的matlab程序，强烈推荐给大家.(individual master's thesis on digital receiver modulation and demodulation of Matlab procedures, We strongly recommend to.)

PID control simulation(matlab simulation for pid controller)

说明：  电力电子变换器采用重复控制策略。在反馈回路中设置一个内部模型，使该内部模型能够很好地描述系统外部信号特性，通过该模型的作用可使系统获得理想的指令跟踪特性，具有较强的扰动抑制能力。(Repetitive Control Strategy for Power Electronic Converter.An internal model is set up in the feedback loop, which can describe the external signal characteristics of the system well. Through the function of this model, the system can obtain ideal command tracking characteristics, and has strong disturbance rejection ability.)

PSO算法和最速下降法混合算法，求解单目标优化问题，测试函数是非线性方程组，解决MinF(x)的问题。(PSO algorithm and steepest descent method hybrid algorithm for solving single-objective optimization problem, the test function is non-linear equations, solving MinF (x) of the problem.)

说明：  用来对图书馆排队借书的情况进行仿真，假设有2个对列时的仿真程序见源代码，用的MatlAB写的(Library queue library used to simulate the situation, assuming there are two pairs of columns in the simulation program, see the source code, written with the MatlAB)

this is matlab code that in it the pid method linear control is developed.the equation of motion is solved with runge-cuta method.

The aim of this paper is to describe a novel and completely automated technique for carotid artery (CA) recognition, far (distal) wall segmentation, and intima–media thickness (IMT) measurement, which is a strong clinical tool for risk assessment for cardiovascular diseases. The architecture of completely automated multiresolution edge snapper (CAMES) consists of the following two stages: 1) automated CA recognition based on a combination of scale–space and statistical classification in a multiresolution framework and 2) automated segmentation of lumen–intima
