这两天着迷goolge earth抓图，编写了一个拼图的程序，主要是用到了imread imwrite和对话框几个知识点，很简单的。(This two-day fascination with goolge earth drawings, prepared a puzzle procedures, mainly used in the dialog box imread imwrite and several knowledge points, very simple.)

根据隐马尔可夫模型，利用马尔可夫链前向算法，用于估值问题。(HMM-FORWARD )

Matlab 实例-编写M脚本文件，涉及比较深层的 MATLAB 内容：脚本；函数（一般函数、内联函数、子函数、私用函数、方法函数）；程序调试和剖析；数据结构（类、对象）；重载和继承；面向对象编程。本章配备了许多精心设计的算例。这些算例是完整的，可直接演练的。读者通过这些算例，将真切感受到抽象概念的内涵、各指令间的协调，将从感知上领悟到面向对象编程的优越和至关要领。(Matlab Examples- the preparation of M script file, involving comparison MATLAB deeper content: script function (general function, inline function, Functions, Private Functions, methods, functions) program debugging and analysis data structure (class, object) Overloading and inheritance object-oriented programming. This chapter with a number of carefully designed examples. These examples are complete, can directly exercise. Through these examples the reader will really feel the meaning of abstract concepts, the coordination between commands from realizing that the perception of object-oriented programming and to the superior customs essentials.)

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.)
