本源码使用eclipse开发。可以统计某个文件夹下具有某一后缀名所有文件的行数。可以用来统计源代码行数来了解自己的开发规模-use eclipse the source development. Statistics can be a folder with a particular suffix all in the name a few. Statistics can be used to a few source code to understand their development scale
用java编写的用蝶式算法实现的fft,用来计算两个多项式的乘积,输入文件的格式如压缩包中的data5.txt,结果输出到result.txt中。-java prepared with the use of the butterfly fft algorithm, used to calculate the product of two polynomials. input file formats such as compressed data5.txt the results were exported to result.txt.
