这篇博客介绍了如何在MATLAB中解决方程，通过`solve`函数遇到参数化解决方案的警告，并提出使用`fmincon`优化器作为替代求解策略。

用matlab解方程

s=solve(200-200x^(-0.4)-6x,x)

返回：

警告: The solutions are parameterized by the symbols: z2.
To include parameters and conditions in the solution, specify the 'ReturnConditions'
option.
> In solve>warnIfParams (line 500)
In solve (line 356)
警告: The solutions are valid under the following conditions: z2^7 - (100*z2^2)/3 +
100/3 == 0 & -pi/5 < angle(z2) & angle(z2) <= pi/5.
To include parameters and conditions in the solution, specify the 'ReturnConditions'
option.
> In solve>warnIfParams (line 507)
In solve (line 356)

s =

z2^5

help solve中关于z的表述：

Example 12:
syms a x y
[x0, y0, params, conditions] = solve(x^2+y, x, y, 'ReturnConditions', true)
generates a new parameter z to express the infinitely many solutions.
This z can be any
