摘要
把区间算法与正割算法相结合 ,给出了一种新的区间正割算法 ,并证明了其收敛性 .与Newton法相比 ,具有收敛快 ,误差小的优点 ,算例证明了其有效性 .
Combining the interval iterative solution with secant method,this paper proved a new interval secant iterative method and proved its convergence.Comparing with Newton's method,it converged quickly and it reduced errors.The example showed the validity of the proposed algorithm.
