The first time I heard about Matlab I thought it would be an additional class requirement that I did not want to have. Too bad. I guess somethings are meant to be.
Little did I know that the things I found mostly interesting in my Calculus III courses had all to do with it. To be honest, I always had a thing for mathematics in general.
It's really interesting to see how life has gone from the many different points I look back to. A lot had been dealt, for good, and some that I've taken for granted.
Perhaps, I didn't take it for granted. I just always felt too humble to take such opportunities as I was given so early in life. Responsibility for saying such big words is not little.
After having produced my first term project, and early this month finally attempting to understand all that information meant was hard.
However, the application of one essential thought, a circular discretization, an orthogonal <-> polar coordinate association, would allow for the development of a new way of doing data analysis.
It was September 27th that I posted the Musical Nautilus up... This is the story of the thoughts behind it!
I hope you enjoy it, ARGouveia anagouveia@engineer.com

Think about a Musical Clock. Each angle line (30, 60...) across theta, shows all the frequencies for the 12-pitches marked on the photo. For your reference 0deg = C and 90deg = A .
Within that angle vector, all 9 octaves for each of the pitches form the nodes on the plot.
Imagine it like this: you start pressing the left most key on a 9 octave piano. If you press each individual key, you'd be starting at the lowest frequency of C=17Hz, and would then be plotting each following node on the graph. The pressing of each of those keys, throughout all 9 octaves, with a simple recurrence formula, shows how their distances form, a Musical Nautilus.
