切比雪夫多项式求函数的最小最大值 怎么用
如何使用切比雪夫多项式求一个函数在给定区间内的最大值的最小值?
这个给定区间一定要是[-1,
切比雪夫多项式求函数的最小最大值 怎么用
First to express the aiming function in terms of the Chebyshev polynomials. Then find the extremal values according to the expression. Sometimes one may consider the trigeometric expressions of Chebyshev polynomials, such like sin((n+1)a)/sin(a) for Chebyshev polynomials of the second kind. This trick converts the original problem into a trigeometric funtion problem.
再问: wiki上面的吗?
再答: after tansforming the problem in terms of Chebyshev polynomials, u can find a huge number of properties by google. Wiki is a good source among.
再问: 有中文的吗?看不懂啊
再答: after tansforming the problem in terms of Chebyshev polynomials, u can find a huge number of properties by google. Wiki is a good source among. 把问题转化成Chebyshev多项式以后,你可在google上找到很多相关性质,其中Wiki是一个不错的来源。
