说明：  本程序用于对相机的标定，通过程序可以运算出相机的参数。对初学者有一定帮助(The procedure used for camera calibration, through the program can calculate the camera parameters. Certainly be of help for beginners)

参加数学建模学生必学软件语言之一，笔者自己总结的lingo笔记，方便学习阅读参考补充。(Students will learn to participate in mathematical modeling of software languages​ ​ , the author summarizes the lingo own notes, easy to learn to read reference supplement.)

Matlab GUI using UICONTROL Function

这是一次，二次，三次bezier曲线用MATLAB实现的程序。(This is the single, double or three times to achieve bezier curve using MATLAB procedures.)

不考虑多径干扰时在高斯白噪声和瑞利衰落信道条件下QPSK的调制解调过程， 并采用准分析法完成误码性能的计算。仿真过程包括仿真信号产成，滤波器设置，QPSK调制，加入高斯白噪声，通过锐利信道衰落，QPSK解调，误码率计算等几部分(Not consider multi-path interference at the white Gaussian noise and Rayleigh fading channel under the conditions of the QPSK modulation and demodulation process and the use of quasi-analysis method to complete the calculation of BER. The simulation process includes the middle class into a simulation signal, filter settings, QPSK modulation, by adding Gaussian white noise, through the sharp decline in channel, QPSK demodulation, bit error rate calculation and other parts)
