使用C 语言编制Mex算法程序，对于提高算法的性能有很大帮助。 希望该文档能帮助大家进入matlab 和 c 语言之间互动的世界，也期待你编制更多的原创程 序奉献给研学论坛，尤其是混沌和分形版面(The use of C language algorithm Mex procedures, for improving the algorithm performance of much help. I hope the document will help us to enter the matlab and c language of interaction between the world, and also look forward to your program to produce more original Forum dedicated to research, especially the chaotic and fractal layout)

佛洛伊德方法用二值模型来形成多灰度图像的真实效果，希望分享(Digital halftoning is the process of converting a continuous-tone images into strictly black and white images such that, when viewed by the human visual system, the pattern creates an illusion of being a continuous shade of gray. )

利用matlab建模的不带ABS的车体子模块，很有参考价值(Using matlab modeling of the body without the ABS module, useful reference)
