Personal Profile:

I love MATLAB. I love teaching people to love MATLAB.

I love it so much that I went to work for the people who make MATLAB. I spend my days at MathWorks creating material to help people learn MATLAB. Life is good.

(My love of teaching MATLAB notwithstanding, please don't email me for help -- post a question to MATLAB Answers instead. Firstly, your email will probably be swallowed by my spam filter. Secondly, private consulting isn't in my job description.)

Thanks for that, Mohammad. Dumb copy-paste error on my part. I've submitted a corrected version.
10 Nov 2011 Simple real Fourier series approximation Computes coefficients for the real Fourier series approximation to a data set. Author: Matt Tearle

The expansion is in terms of sin/cos(kx) for k = 0:n, so the frequencies are simply k/L (for k from 0 to n), where L = max(x) - min(x). The units would be in inverse units of x. In the example given in the description, you can see the dominant contribution from the 4th sine term, which corresponds to a frequency of 4/(2-0) = 2 Hz (if x represented time in seconds).

Thanks for the feedback, too. Glad it could help.

Great App. However, I have found one bug here. When you change the threshold value of G and B channel, the changed value is always reflected to the R channel instead of being reflected to the corresponding channels.

Does anyone know if there is a way to extract a_o , a_n, and b_n from the command line or the script in the more general cos and sin terms?
