该程序为fftw的简化高效版，fftw为MIT的开源fft程序，功能非常强大。包括范围也很广。这个为简单版本。-The program for high-performance version of fftw simplified, fftw for MIT s open source fft procedure, very powerful. Including a very wide scope. This for the simp

32位FFTW调用函数库，可通过C++编译生成-32 calling FFTW library, compiled by C++

实现各种数字信号处理的类库，比如快速傅立叶变换fft，还有其他多种信号变换 ，使用C++ 库(To achieve a variety of digital signal processing class library, such as fast Fu Liye transform, FFT, there are many other signal changes, using the C++ Library)

此变换库使用平台为windows系统，安装完毕后可以在IDE里面调用FFTW函数实现数据的FFT变换。(The transformation library uses the platform as the windows system, and after installation, the FFTW function can be called in the IDE to realize the FFT transform of t
