分形差值函数是由迭代函数系统IFS实现的，通过离散的数据点构成分形插值函数，证明分形插值函数是这个IFS唯一吸引子。利用MATLAB矩阵运算，实现数据点的分形差值拟合。该算法简介直观。(The fractal difference function is implemented by the IFS fractal interpolation function through the data points of the discrete prove fractal interpolation function only attractor of the IFS. Fractal difference fitting using MATLAB matrix operations, the data points. The algorithms Profile intuitive.)

这是一段拟合函数的MATLAB程序，需要的同学可以下载看看(It was a fitting function of the MATLAB program, students in need can be downloaded to see if)

说明：  值得深刻阅读的基于CP的OFDM同步程序 这是一个非常好的用于OFDM的基于CP的 最大似然符号定时同步和载波同步的MATLAB仿真程序，经本人深入阅读吸收经典文献，反复编程调试而提炼而成，代码精炼有序，绝对没有错误，由此程序仿真得到的同步曲线与经典文献完全一致。同仁们阅读此程序一定受益匪浅！ 这里不吝成果，特上载与诸位网友共享。也欢迎同仁们提供更多的优秀程序。 由于文献要求采用N＝1024个子载波的OFDM，运行此程序需2分钟－3分钟的时间。 (Worthy of profound reading of the CP-based OFDM synchronization process this is a very good CP for OFDM-based maximum likelihood symbol timing synchronization and carrier synchronization of the MATLAB simulation program, after I read the absorption of classical literature in depth, repeated programming and debugging extracted from the symbol of refined and orderly, there is no error, this procedure has been synchronized simulation curve is fully consistent with classical literature. Tongren have read this procedure will definitely benefit! Spared the outcome here, especially to upload to share with you friends. Tongren also welcome to provide more excellent program. Documentation required as a result of N = 1024 sub-carrier OFDM, to run this process will take 2 minutes-3 minutes.)

A Gabor-filtering method for describing textural features is proposed, which applies the physical properties of a probability wave to probability transformation, and computes textural features 2) An adaptive strategy for feature and filter selection, and feature weighting, is proposed, which utilizes a user’s relevance feedback to reduce the redundancy in the representation and incorporate the user’s information needs in image retri 3) Integrating both schemes (the Gabor-filtering method and the adaptive strategy) for content-based mammogram retri is suggested
