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?

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
再问: 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··
再答: >> [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 还是可以算
