CurveLab-1.0工具箱，附带一些demo(CurveLab-1.0 toolbox，with some demo)

(1) 新建一个工程demo2，设计一个类Student，其成员变量包括学号(no)、姓名(name)、性别(sex)、专业(major)、联系方式(phone)和地址(addr)。 (2) 为类Student定义成员函数writeTo，实现从给定文本文件中读取学生数据，接口如下： void writeTo (char filename[ ]) (3) 为类Student定义成员函数readFrom，实现将学生数据保存到给定文本文件，接口如下： void readFrom (char filename[ ]) ((1) Create a new project demo2, design a class Student, whose member variables, including school (no), name (name), gender (sex), specialty (major), contact details (phone) and address (addr). (2) define the Student class member function writeTo, students achieve reading data a given text file, the interface is as follows: void writeTo (char filename []) (3) define the Student class member function readFrom, students will achieve data save to text file given, the interface is as follows: void readFrom (char filename []) )

根据)EF 特性中的对比度敏感度， 即空间频率特性曲线，对图像进行二维多级小波分解，由分解后的各小波分量，提取各频段相应的亮 度、清晰度和相关度指标；然后将这三个指标的几何平均与频段加权系数的内积做算术平均，以此作 为图像质量的综合评价指标(According to) EF characteristic of contrast sensitivity, that is spatial frequency characteristic curve, the image is two-dimensional multi-level wavelet decomposition, the decomposition of the wavelet component, extract the frequency band corresponding brightness, clarity and relevance of indicators then the geometric mean of these three indices and the band doing weighted coefficient of the arithmetic mean within the product as a comprehensive evaluation of image quality index)

comfac算法是三线性模型常见的数据检测方法。它首先将三线性数据通过tucker3模型压缩，然后通过最小二乘的方法不断更新数据，直到收敛，得到估计值( The algorithm works by first compressing the data using a Tucker3 models. Subsequently the PARAFAC model is fitted to the compressed array, either initialized with DTLD (~ESPRIT) or with PARAFAC-ALS. The solution is de-compressed to the original space, and a few safe-guard PARAFAC-ALS steps are performed. Further optimization of this algorithm is possible, e.g. if the data are very large, if the profiles are very correlated or if the noise is huge. This 、 has not been pursued here, in order to have a generally applicable algorithm)

说明：  Theoretical analysis and experimental results show that the algorithm has large key space, high sensitivity, and high speed.
