摘　　要：根据牛顿切线法求方程的根的思想,结合2008年数学建模A题,运用迭代法求两凸集(椭圆)的公切线,算法简洁实用,可操作性强。并证明了算法对公切线的收敛性和收敛速度。According to Newton's equation of the tangent method the root of thinking, combined with mathematical modeling A title in 2008, using the iterative method for two convex sets(oval) common tangent, the algorithm is simple and practical,workable. And proved common tangent algorithm convergence and convergence rate.
