matlab解线性方程组,为什么得不到正确结果
[k,a11,a12,a21,a22]= solve('-0.0104=0.0420/(0.2651*k+1)*(-12.5*a12)','-0.0104=0.0420/(0.2651*k+1)*(-12.5*a22)','-0.0178=0.0420/(0.9853*k+1)*(20*a11-12.5*a12)','-0.0260=0.0420/(0.9853*k+1)*(20*a21-12.5*a22)','0.0394=0.0394/(0.8802*k+1)*(20*a11-12.5*a12)')
[k,a11,a12,a21,a22]= solve('-0.0104=0.0420/(0.2651*k+1)*(-12.5*a12)','-0.0104=0.0420/(0.2651*k+1)*(-12.5*a22)','-0.0178=0.0420/(0.9853*k+1)*(20*a11-12.5*a12)','-0.0260=0.0420/(0.9853*k+1)*(20*a21-12.5*a22)','0.0394=0.0394/(0.8802*k+1)*(20*a11-12.5*a12)')
能得到结果：
k =

a11 =
