MATLAB求非线性方程组

各位大神能帮忙用MATLAB解一下这个方程组吗？

z^2*y*x^-2-10=0
x*f*y^(-1)*e^(-1)-20=0
g*z*f^(-1)-25=0
h*e*g^(-1)*z^(-1)-15=0
x+2*y+f+g+h-10000=0
x+2*y+e+2*f+2*g+h-40000=0
4*x+4*y+2*z+2*e+2*f-100000=0
未知量是x,y,z,e,f,g,h七个，方程也有七个。

用solve没有得出结果

数值分析的内容，去翻翻书吧。

第一个方程是：
z^2*y*x^(-2)-10=0吧，如果是的，得到以下几组解：
x: 7741.46278961098
y: 30.0054210478678
z: 4469.13185411458
e: 27830.5431582258
f: 2157.38856634195
g: 12.0682754322617
h: 29.0695265190726

z: 59.8904159254318
y: 16870.2577771186
x: -2459.90416879671
f: 21274.5074352385
e: -155.105067807618
g: 8880.59763256915
h: -51435.716453248

嗯嗯是这个方程

可以麻烦看一下写的程序吗
十分感谢！
