No, it was patented by the professor who invented it. Fortunately there is another algorithm that is faster and performs about as well called SURF. It is in the Computer Vision System Toolbox: http://www.mathworks.com/help/vision/functionlist.html

One could argue that although SURF maybe faster than SIFT, it is not as accurate.
