MATLAB和maple语言均未直接提供求解fourier级数的系数的直接函数，自己动手丰衣足食，下面提供了一个代码，大家可以参照下 (MATLAB language, and maple were not directly solve the fourier series coefficients of the direct function, it-yourself ample food and clothing, the following provides a code, we can refer to the next)

这个小程序可以简单的选取回归分析中box-cox变换的lambda值，通过matlab强大的矩阵运算功能可以通过简单比较RSS值的方式来得到lambda，使用时只需要输入实验值矩阵X和Y即可，然后输入minRSS（X，Y）就能简单明了的看到最优变换参数 （这个程序虽然小但是学习回归分析的初学者学习时都会经过这个算法，上载时因为不到1KB所以我又放了个文本格式的）(This little program can select a simple regression analysis of box-cox transformation of lambda values, through the powerful matlab function matrix calculation can be relatively simple way of RSS to get the value of lambda, the use of only need to enter the experimental data matrix X and Y can be , and then enter the minRSS (X, Y) will be able to see the simple optimal transformation parameters)

摘　要:针对茄子图像的灰度和颜色特点,利用MATLAB中丰富的图像处理函数,分别进行了色差分割和色调分割。在 色调分割中,采用了自动选取阈值的Otsu法。在去除残留噪音的处理中,采用标注的方法对二值图像的各连通区域进行面积 统计。保留最大面积的区域,从而使分割效果大大改善。利用多参数来衡量分割效果,使评价做到最大程度的客观、合理。(Based on the gray- level and color characteristics of eggp lant image, hue and color- difference segmentation were conducted by using the rich image p rocessing functions embedded inMATLAB. The auto threshold- adap tivemethod ofOtsu operation was specially used for hue segmentation. And upon the elimination of the residue noise, labelingmethod for statistical calculation was introduced for the connected regions of the binary image. Themaximum areaswere p reserved to imp rove segmentation effects. In addi2 tion, multi- indiceswere app lied to assess the effect of segmentation, in order to get impersonal and reasonable assessment)
