Fminsearch不承认的约束限制。

不过简单的转换方法存在

转换成一个绑定的约束问题

无约束问题。

Fminsearchbnd用于酷似fminsearch，

除了边界应用到变量。

应用于国内的界限，利用

改造中的变量。 （二次型

单式，双罪恶界（十）。）

具有包容性的不平等的界限，它承认

边界值本身，但不准

在所有函数之外的范围评估。

请注意，fminsearchbnd允许用户准确地固定在某个给定值通过设置一个变量的确切范围相同的值。

-Fminsearch does not admit bound constraints.

However simple transformation methods exist to

convert a bound constrained problem into an

unconstrained problem.

Fminsearchbnd is used exactly like fminsearch,

except that bounds are applied to the variables.

The bounds are applied internally, using a

transformation of the variables. (Quadratic for

single bounds, sin(x) for dual bounds.)

The bounds are inclusive inequalities, which admit

the boundary values themselves, but will not permit

ANY function evaluations outside the bounds.

Note that fminsearchbnd allows the user to exactly fix a variable at some given value, by setting both bounds to the exact same value.
