程序里有基二fft时域，频域c代码，还有基4，分裂基算法，实序列fft变换的源程序，都是头文件的形式，我已经在vc++6.0的环境下调试通过。且这些程序的位倒序部分，旋转因子部分采用的是比较快的算法，应该与本网站已有的程序不同，我的算法较快。-procedures there are two fft-time domain, frequency domain c code, there are four-and split-based algorithm fft transformation sequence is the source, are the first in the form of a document, I have vc 6.0 environment through debugging. And these procedures-part of the reverse order, rotating part of the factor is relatively fast algorithm, This site should have different procedures, I algorithm faster.
