matlab学习刚起步，可以进步很快，大家一起学习一下(Matlab is a very useful software, we study together)

本程序是LM方法实现的主程序，并且本程序通过了LMFnlsq2test.rar程序的测试，证明了程序的正确性和有效性。顺便说下，上面的LMFnlsq2test.rar里面的程序是一个测试程序，它的描述写错了。(This LM method is the main program, the program and the program passed LMFnlsq2test. Rar program test, proves the correctness and effectiveness of the program.. By the way, the above LMFnlsq2test rar program is a test program, a description of the write it wrong.)

am fine and i feel to in joy that

电子稳像灰度投影算法的电子稳像算法，针对最近matlab2013a进行了修改，使得程序可以适应更多视频格式，可直接运行，效果良好(Electronic image stabilization gray projection algorithm electronic image stabilization algorithm was modified for the recent matlab2013a, so that the program can accommodate more video formats, can be directly run to good effect)

说明：  这是关于支撑向量机算法的matlab程序(This is on the support vector machine algorithm matlab program)
