qrs detection in ECG signals

this is matlab code for pprobality theory which is implemetatde in matab 7,6

use matlab to draw the topology of an inductor for IC design.you only need to type in your expected size of the ind,then it will give you a .cif that can be used in many IC simulators.

这是一个简单的多用户蜂窝无线通信系统的建模与仿真(This is a simple design of cellular radio systems for multi-user )

利用GNSS 进行高精度导航定位的前提是正确固定载波相位观测值的整周模糊度。由Galileo 系统的4 个载波观测值可以 形成诸多有良好特性的组合观测值,利用这些组合观测值,结合MCAR 方法,可以有效地确定整周模糊度。(The use of high-precision GNSS navigation and positioning the premise is correct carrier phase observations fixed integer ambiguity. May consist of four carriers observations Galileo system There are many good characteristics to form a combination of observations using a combination of these observations, combined with MCAR method can effectively determine the integer ambiguity.)

一种间接的估计信号的1.5维谱的方法，1.5维谱可以有效的抑制高斯噪声，加强低频分量。(An indirect estimate of the signal spectrum of 1.5-dimensional method, 1.5-dimensional spectrum can effectively suppress Gaussian noise, to enhance low frequency components.)

根据人口趋势模拟未来航天系统需求增长趋势(Simulated future aerospace systems based on population trends in demand growth)

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)

利用matlab控制3维仿真软件sonnet的工具箱，里面包含了详细的试用说明PDF，还有一个微带天线的例子，使得对天线的设计变得简单。(Using matlab to control 3-D simulation software sonnet Toolbox, which contains a detailed description of the trial PDF, there is a microstrip antenna example, makes the simple antenna design.)
