matlab解二元方程··我用的matlab7··大神帮帮忙·总算不出开
[x,y]=solve('x*exp(-y/(1.38*600))=776','x*exp(-y/(1.38*1073))=96000000','x','y');
错误为:'Explicit solution could not be found.'
[x,y]=solve('x*exp(-y/(1.38*600))=0.0000776','x*exp(-y/(1.38*1073))=9.6','x,y')··同一单位去掉小数点什么的·就成这样··不出错了·可是也不出结果

答案
>> [x,y]=solve('x*exp(-y/(1.38*600))=0.0000776','x*exp(-y/(1.38*1073))=9.6')
x =
27668608.330140654033638394310398
y =
22024.594810018609390611284956502
%[x,y]=solve('x*exp(-y/(1.38*600))=776','x*exp(-y/(1.38*1073))=96000000') 无解
x =
27668608.330140654033638394310398
y =
22024.594810018609390611284956502
%[x,y]=solve('x*exp(-y/(1.38*600))=776','x*exp(-y/(1.38*1073))=96000000') 无解
举一反三
已知函数f(x)=x,g(x)=alnx,a∈R.若曲线y=f(x)与曲线y=g(x)相交,且在交点处有相同的切线,求a的值和该切线方程.
