Description: This function is written to understand and/or explain an fft algorithm and usage of radix2 procedure.
This function take the signal which you want to find FFT, for m bit
you can also call the function without entering a signal or number of points, because there is default values for y and m which are
y = sin(2*pi*50*t)+sin(2*pi*120*t)
m=3
you can see the steps of order reversing used as built-in function but non others. you will also see the taking butterfly tree steps.
for more information read the help file of function.
in future this can be improve as selective radix or any other feature you suggest please notice me for any sugestion.

Description: FFT算法实现
Radix2 可以计算 4，8，16，32, 64，128, 256....点FFT
Radix4 可以计算 4，16, 64, 256, 1024...点FFT
FFT_DIT_general.c 实现了 Radix2 和Radix4 的配合使用，可以计算Radix2可以计算的所有FFT，但效率比Radix2高。-FFT can be calculated Radix2 algorithm 4,8,16,32, 64,128, 256 .... can calculate the FFT Radix4 points 4,16, 64, 256, 1024-point FFT FFT_DIT_general.c ... Radix2 and Radix4 achieved with the use of Radix2 can calculate can calculate all the FFT, but Radix2 high efficiency.

Description: fft The radix-2 algorithms are the simplest FFT algorithms.
The decimation-in-time (DIT) radix-2 FFT recursively partitions
a DFT into two half-length DFTs of the even-indexed and odd-indexed
time samples.
The outputs of these shorter FFTs are reused to compute many outputs
