产生随机数，然后计算概率,一个非常实用的MATLAB程序(this brief program can generate some random numbers and calculate the probability)

MATLAB的mmread函数，用于读写与视频相关的文件(MATLAB-mmread functions for reading and writing and video-related documents)

This example shows how to generate C code for a MATLAB Kalman filter function, Kalman , which estimates the position of a moving object based on past noisy measurements. It also shows how to generate a MEX function for this MATLAB code to increase the execution speed of the algorithm in MATLAB.

通过对抽油杆运动规律的分析并结合简易的几何图形，计算出光杆悬点运动的位移函数，从而得出光杆运动的速度函数和加速度函数，并且通过MATLAB软件给出了位移函数图象，及其与有荷载的附件1的悬点位移数据的比较图。(Through the analysis of the sucker rod motion law and combining the simple geometric shapes, calculate the polished rod suspension point displacement function, calculated the functions and the acceleration of the polished rod motion speed, and displacement function is given by MATLAB software image, and its suspension with a load of attachment 1 point displacement data comparison chart.)
