UC知道matlab求解参数方程

方程:'a*x^3-b*y^2=0','exp(a*x^2)-y-1=0
我把 [a,b]=solve('a*x^3-b*y^2=0','exp(a*x^2)-y-1=0','a,b')输入matlab为什么出现 [a,b]=solve('a*x^3-b*y^2=0','exp(a*x^2)-y-1=0','a,b') ??? Error using ==> mupadinit at 35 Unable to initialize kernel Error in ==> mupadengine.mupadengine>mupadengine.evalin at

我是matlab初学者,按照上面这么输的,格式应该没错吧?用的是matla

我也用你的运行了下，是matlab7.1的
>> [a,b]=solve('a*x^3-b*y^2=0','exp(a*x^2)-y-1=0','a,b')
a =
log(y+1)/x^2
b =
log(y+1)*x/y^2
>> 这是运行的结果，你看看是不是你在以前的程序中有了 这个变量名什么的，都清空了试试
[a,b]=solve('a*x^3-b*y^2=0','exp(a*x^2)-y-1=0','a,b')
我的运行结果：
a =log(y+1)/x^2
b =log(y+1)*x/y^2
你用的是2009的版本吗？听说与360冲突的http://help.360.cn/5030804/22713366.html
装最新的360试试，360的工作人员说是解决了问题，实在不行卸360
如果是7.0较早的版本的话应该没问题，关了再进去运行看看
上面是我用7.1运行得的结果
