字號:
function [z,e] = rootsl(p)% function [z,e] = rootsl(p)%% computes the zeros z of the polynomial p (descending % order). It yields results with higher precision in much% less time (especially for large degrees) than the % built-in function roots. e is an estimate for the maximum% relative error of all roots. maximum degree is 10000. %% author: m.lang & b.frenzel, 15.6.1993?? 快捷鍵說明
