给定x/(1-x+x^2)=x+x^2-x^4-x^5+x^7+x^8-x^10-x^11+x^13+。。。
形成x/(1-x+x^2)迭代中的系数表,如下所示:
[1, 1, 0, -1, -1, 0, 1, 1, 0, -1, ...];
[1, 2, 2, -1, -8, -15, -10, 22, 79, 112, ...];
[1, 3, 6, 6, -11, -73, -201, -309, 37, 1913, ...];
[1, 4, 12, 26, 24, -116, -808, -3000, -7566, -9882, ...];
[1, 5, 20, 65, 155, 120, -1379, -10761, -51202, -183269, ...];
[1, 6, 30, 129, 464, 1225, 702, -18978, -169139, -994138, ...];
[1, 7, 42, 224, 1057, 4235, 12411, 4445, -301321, -3076795, ...];
[1, 8, 56, 356, 2064, 10752, 48000, 156416, 27812, -5458012, ...];
[1, 9, 72, 531, 3639, 23064, 132633, 658197, 2388060, 187911, ...];
[1,10,90,755,5960,44265,306742,1942198,10676571,43159172,…]。。。
则该序列在上表中形成对角线。
