求助关于符号变量的计算结果的问题
在符号变量的计算过程中,符号变量的系数是一个 很大的分数,我想知道如何化简成最简形式?比如一个符号变量的结果如下
28544953854119202593525972496744320000/1427247692705960025784236001705007*y+5534023222112865484800/73786976294838200321+856348615623575889883579789414527664128000/1427247692705960025784236001705007*x^2*y-221360928884514619392000000/73786976294838200321*x^2+285449538541192023740817577202967956684800/1427247692705960025784236001705007*y^3
其实这个变量的系数都是整数,可是结果显示成这个样子,有没有办法可以解决这个问题?? help vpa

3q楼上,我去看看 支持,楼主,可是我好像看不太懂 >> syms x y>> z=28544953854119202593525972496744320000/1427247692705960025784236001705007*y+5534023222112865484800/73786976294838200321+856348615623575889883579789414527664128000/1427247692705960025784236001705007*x^2*y-221360928884514619392000000/73786976294838200321*x^2+285449538541192023740817577202967956684800/1427247692705960025784236001705007*y^3
z =
20000*y+75+5033164799999999/8388608*x^2*y-6442450944000001/2147483648*x^2+200000000*y^3
or help simplify
