简单解方程问题,大侠帮忙!

<P>y.为一行,2410列阵,现在我要求s阵为何老报错:<BR>is not a valid expression or equation.</P>
<P>s=solve(['2*(log(y./0.1601304))=-2*log(x.)+(2.073447/0.073447)*log((2/2.073447)*(1+(0.073447/2)*x.^2))']) ;<BR></P>

s=solve(['2*(log(y/0.1601304))=-2*log(x)+(2.073447/0.073447)*log((2/2.073447)*(1+(0.073447/2)*x^2))']) ;<BR><BR>不过你这个方程积分不存在
