THE TEACHING OF PADéAPPROXIMATION IN NUMERICAL ANALYSIS
摘要
Abstract
Padéapproximation and the rational interpolants are used to approximate the function 11+25x2 defined on [-1,1]. By comparing the result with the polynomial interopolation, the two methods can accurately approximate the function. Then the vector-valued continued fraction is presented and utilized to accurately approximate the arc. This work above can deepen stu-dents'intuitional impression of Padéapproximation and enhance the teaching effect.关键词
