truncation_filtering

Control optimisation. It is example of use BFGS algorithm to control satellite form Earth atmosphere to the Mars. Controled is engine power (bang-bang type) and angle of nozze.

最近总是在这下程序，觉得也应该贡献一下，分数阶傅立叶变换的一个matlab程序(Always under the most recent in this process, feel that we should contribute about fractional Fourier transform of a matlab program)

The Block-Matching and 3D Filtering (BM3D) algorithm is a computationally scalable algorithm based on this novel denoising strategy. It achieves state-of-the-art denoising performance in terms of both peak signal-to-noise ratio and subjective visual quality.

说明：  Matlab教程，初学者很好的学习材料。拿来分享。(Matlab tutorial for beginners good learning materials. To be shared.)

本学期研一课程开设了数值方法，由于数值计算是MATLAB一项重要功能，所以结合MATLAB学习数值方法也许是条捷径！为了让大家更好的理解课程内容，更熟练第运用matlab解决数值计算问题，我根据上节课的内容，编写了《拉格朗日多项式逼近》与《牛顿多项式逼近》程序，以抛砖引玉，和大家共同提高！（其中部分程序参考数值方法（MATLAB版）一书） 附件里有m文件和详细的使用方法！ 希望让大家受益！(Lagrange polynomial approximation)

this matlab code is useful for hill climbing algorithm.
