Support Vector Machines

　　I have some issues to state. First, there were some bugs in original code which may be caused by versions. I don\'t know... 

　　There are three pictures u need to draw a division boundary. The first calls \'visualizeBoundaryLinear.m\' which is fine, but the others which call \'visualizeBoundary.m\' can not 

draw boundaries. So I check out this file and change the code \'contour(X1, X2, vals, [0 0], \'Color\', \'b\');\' to \'contour(X1, X2, vals, [0.1 0.1], \'linecolor\',\'b\');\', then it turn out to work!

　　Second, It\'s fun to achieve the SVM for spam-email filter. Everything about it is in ex6.pdf. U should learn more about this.

　　Finally, my code is also in gitlab which you can click here to get it.

　　It is really fansinated to see all functions run in a correct way!
