无单元法详尽描述，进展，各步骤的matlab实现，学习element free method 的好资料(A review and computer implementation aspects for meshless method)

matlab GUI的例子，个个都是经典，大家都下载来学习(All of the handles to the various objects created in each GUI, as well as data needed to run the GUI, are stored in a main structure called S. The fieldnames for handles are in lower case letters, and the fieldnames for data are in uppercase letters. Callback function names are designated with the fieldname of the object to which they correspond, followed by _call. Other function names are similarly designated. For instance, a keypressfcn will end in _kpfcn and a buttondownfcn will end in _bdfcn. The code of each GUI is generously commented, and subtle points may be examined in the comments (see for example the last comment block in GUI_32). If anything seems unclear, look first in the comments, and if satisfaction is not found there feel free to email me.)

说明：  数学建模大赛常用的建模模型，对全国建模大赛很有帮助的啊！(Modeling Mathematical Modeling Contest common model of the national modeling contest helpful ah!)

this package include moving object detection and hough transform to recognise parallel line in an image. a sample image included in package for test.
