基于MATLAB写的调试通过的QRS检测算法，具有信噪比估计、阀值预测的斜率检测算法。(Written based on MATLAB debugging through the QRS detection algorithm, with SNR estimation, prediction of the slope threshold detection algorithm.)

说明：  这是MATLAB 图形用户界面的一个例子 欢迎大家一起交流学习心得 我也是刚刚接触MATLAB(This is a MATLAB graphical user interface with an example welcome everyone to exchange learning experiences I have just contacted MATLAB)

利用光滑牛顿法求解二次规划子问题，以下为代码(Smooth Newton method using quadratic programming sub-problems, the following code)

该文件是包括正弦信号通过加性噪声信道的时域输入波形和输出波形图(The file includes a sinusoidal signal by the time domain input and output waveforms of the additive noise channel)

一个简单的四则运算计算器，它能实现两个数据的加减乘除运算，数据需手动输入。因为界面相对简单，方便初学者使用学习(A simple four-function calculator, it can achieve two data arithmetic operations, data to be entered manually. Because the interface is relatively simple and easy to learn for beginners)

分数阶传递函数的类描述，绘制bode图、nyquist图(fractional order system， bode )

该程序主要用于实现施密特正交化过程，能够较好的完成程序运行(The program is mainly used to achieve Schmidt process, better able to complete the run)

3条固定路径的AWGN多径信道中的QPSK系统进行BER性能仿真，并与理想信道(没有多径)作比较。 需要的支撑子程序为qpsk_berest.m,vxcorr.m,random_binary.m.(Three fixed-path multipath AWGN channel QPSK system BER performance simulation, and with the ideal channel (no multipath) for comparison. Need the support of subprogram for qpsk_berest.m, vxcorr.m, random_binary.m.)

LMS自适应算法，权的迭代及画性能表面的等高线绘图。(LMS，dsp)
