概率计算问题之前向算法

本文介绍在研究生阶段研究的最新卷积程序，希望有用。(This article describes the stages of postgraduate study at the latest convolution process, seek to help.)

基于MATLAB／Simulink环境下的PID参数整定(PID parameters based on MATLAB/Simulink environment setting)

该程序完成一个16电平PAM数字通信系统的仿真，并测量了它的误码率。首先产生信息符号序列，该序列被当做4个信息比特一组，将16组符号映射到16个信息幅度。检测器计算距离，输出与真正传输的信息符号序列作比较，然后将差错计数。( This procedure completes a 16 level PAM digital communication system s simulation, and has surveyed its error rate. First has the message digit sequence, this sequence is treated as a 4 information bit group, maps 16 class symbols to 16 information scopes. The detector estimated range, the output and the true transmission s message digit sequence does compares, then counts the mistake. )

这是pcnn用于边缘检测的matlab源代码，希望对大家有用。(edge detection for the Matlab source code, we hope that the right useful.)

直方图均衡法的MATLAB图，经过测试没有问题，绝对可以用，做图像的同学可以用来参考.大家可以下载下来在MATLAB中运行试试(Histogram equalization method of MATLAB figure, after test no problem, absolutely, can be used to do image can be used for reference)

For inverting a matrix, Gauss-Jordan elimination is about as efficient as any other method. For solving sets of linear equations, Gauss-Jordan elimination produces both the solution of the equations for one or more right-hand side vectors b, and also the matrix inverse A(-1). However, its principal weaknesses are (i) that it requires all the right-hand sides to be stored and manipulated at the same time, and (ii) that when the inverse matrix is not desired, Gauss-Jordan is three times slower than the best alternative technique for solving a single linear set.

采用MATLAB GUI 设计的加法器界面，输入两个数，实现两数相加的功能，适合于刚刚接触的同学。(Using MATLAB GUI interface design adder, enter two numbers, two numbers together to achieve the function, just contact for students.)
