目前网络关于分数阶傅里叶变换可靠的代码来源主要有一下几个：（1）来源一：M.A.Kutay.fracF:FastcomputationofthefractionalFouriertransform,1996.www.ee.bilkent.edu.tr/~haldun/fracF.m.（2）来源二：J.O’Neill.DiscreteTFDs:acollectionofmatlabfilesfortime-frequencyanalysis,1999.ftp.mathworks.com/pub/contrib/v5/signal/DiscreteTFDs/.（3）来源三：AdhemarBultheelandH´ectorE.Mart´ınezSulbaran.frft:ComputationoftheFractionalFourierTransform,2004.www.cs.kuleuven.ac.be/~nalag/research/software/FRFT/.（4）来源四：A.Bultheel.frft2:Atwo-phaseimplementationofthefractionalFouriertransform,2011.这里比较推荐的是来源三及其网站。
2004年的这篇文章《ComputationoftheFractionalFourierTransform》对前面的（1）和（2）进行了详细的对比，分析了两个程序的优劣并进行了改进，（3）的代码较为简洁也比较实用，其对应网站上还有很多相关的代码。

在日常工作中，钉钉打卡成了我生活中不可或缺的一部分。然而，有时候这个看似简单的任务却给我带来了不少烦恼。 每天早晚，我总是得牢记打开钉钉应用，点击"工作台"，再找到"考勤打卡"进行签到。有时候因为工作忙碌，会忘记打卡，导致考勤异常，影响当月的工作评价。而且，由于我使用的是苹果手机，有时候系统更新后，钉钉的某些功能会出现异常，使得打卡变得更加麻烦。 另外，我的家人使用的是安卓手机，他们也经常抱怨钉钉打卡的繁琐。尤其是对于那些不太熟悉手机操作的长辈来说，每次打卡都是一次挑战。他们总是担心自己会操作失误，导致打卡失败。 为了解决这些烦恼，我开始思考是否可以通过编写一个全自动化脚本来实现钉钉打卡。经过一段时间的摸索和学习，我终于成功编写出了一个适用于苹果和安卓系统的钉钉打卡脚本。
