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)

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!
