关于勒让德多项式的算法问题

THE PROBLEM ON THE ALGORITHM OF LEGENDRE POLYNOMIAL

本文讨论勒让德多项式P_1(x)和缔合勒让德多项式P_(1m)(x)的两种算法,即直接计算和递推算法,并给出相应的计算公式,当1取值较大时,也可以保证达到较高的精度。

Two hinds of algorithms, direct calculation and recurrence met hod, are discussed in this paper,and the corresponding computing formulas which keep higher accuracy for large value of 1, are also given.
