函数简介：此程序包是通用的快速傅里叶变换C语言函数，移植性强，以下部分不依
赖硬件。此程序包采用联合体的形式表示一个复数，输入为自然顺序的复
数（输入实数是可令复数虚部为0），输出为经过FFT变换的自然顺序的
复数.此程序包可在初始化时调用create_sin_tab()函数创建正弦函数表，
-Function Descr iption: This package is a generic fast Fourier transform C language function, portable and strong, the following section does not depend hardware. This package is used to represent a complex form of the Commonwealth, as the natural order of the complex input (input can make complex real number is the imaginary part is 0), output after FFT transform the natural order of the complex. This package can be initialized call create_sin_tab () function to create a sine function table,
