摘要
为了方便地计算n阶第一类Bessel函数(n为整数或者为0时)的函数近似值,本文推荐了一种新的算法,即采用了多项式逼近和C++语言的算法相结合的方法,通过与MATLAB的精确计算结果进行分析,两者的绝对误差都在10e-5,并且该算法具有更高的精度,从而证明该算法的可行性和正确性。
In order to calculate the function approximation of order n primal Bessel function （n is an integer or O） easily, in this paper, a new algorithm-polynomial approximation and C ＋ ＋ language algorithm combined is recommended. The results obtained from the new method are compared with the results of MATLAB accurate calculations. The absolute error in the 10e-5 orders of magnitude, and the algorithm has a higher precision. Comparative analysis of the experimental results to prove the feasibility and correctness of the algorithm.
