RADIX-2 FFT DECIMATION IN TIME

This program implements radix-2 fft decimation in time for any length sequence.

Description

The attached file is the m-file for this program. I have not written any comments. I directly implemented the signal flow graph for a generalized radix 2 fft decimation in time. The program is not that fast when compared to built in function of matlab.
the format for calling the function is
my_fft(x), where 'x' is the row or column vector whose fft is to be found.

• Required Products: Signal Processing Toolbox
• MATLAB release: MATLAB 6.1 (R12.1)

The only use for this function is to provide another student with a homework problem solution. Do not use this function for any other reason.

There is no leading help text in this submission and only a couple comments in the body of the file.

Needs to include a general description of the file. Poor Documentation.
Fairly efficient piece of code.

Yes, this is to help students with their homework.
This helped me a lot, I just wish I could understand 3 lines that I don't know where did they come from.
Thank you very much!
