The Clipper library performs clipping and offsetting for both lines and polygons. All four boolean clipping operations are supported - intersection, union, difference and exclusive-or. Polygons can be of any shape including self-intersecting polygons

在C++ Builder2009下调用Matlab库（v4501b）包含对matlab库的初始化，通过调用matlab接口，进行曲线模拟(In C++ Builder2009, the Matlab Library (v4501b) is called, including the initialization of the MATLAB library, and the curve simulation is done by calling the Matlab interface)
