matlab解二元方程问题，matlab解二元方程问题，求高手解答

solve('x*exp(-y/(1.38*600))-176','x*exp(-y/(1.38*1073))-9600','x','y');不出结果啊，其实其中的9600应该是96000000，这样解不出来，是超区域了，还是算不出来？

Answer 1

可以算没问题，我的matlab版本是2011b
>> [x,y]=solve('x*exp(-y/(1.38*600))-176','x*exp(-y/(1.38*1073))-96000000','x','y');
>> x

x =

1816951809543408.9164618069602354

>> y

y =

24811.394808229991796286159902328

追问

有点问题·错了···公式错了··solve('x*exp(-y/(1.38*600))=176','x*exp(-y/(1.38*1073))=96000000','x','y');应该是这样··等号写成-号了··麻烦你再帮忙算下··
