RADIX-2 FFT DECIMATION IN TIME

28 Nov 2007 (Updated 28 Nov 2007)

No BSD License

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

File Information
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)

28 Nov 2007	Duane Hanselman	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.
23 Jan 2008	Sandeep Radhakrishnan	Needs to include a general description of the file. Poor Documentation. Fairly efficient piece of code.
05 May 2008	John Doe	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!
