最近用Mega128写了一个128点FFT程序,浮点运算,加汉宁窗。由于窗函数和旋转因子通过查表得到,所以速度还可以,程序中给的初值是通过高速AD采集的20KHz正弦信号。计算结果与Matlab的FFT函数得到的结果相同。 (Mega128 recently wrote a 128-point FFT procedures, floating-point operations, Hanning window. Since the window function and the twiddle factor look-up table has been adopted, so the speed can also be, the initial value to the process through high-speed AD collected 20KHz sinusoidal signal. The calculation results with the Matlab)

XMathLib
类似于MatLab的东东,当然肯定没那么好,但基本的数学运算还是有的(MatLab is similar to the East, of course, is not so sure, but the basic arithmetic or some)
