Fourier

Jonathan Foote

OK need help here. This recomputes the entire fourier transform on any change of freq1 and freq2. using calcXformArray, which is expensive. What I really want is to just display and store the result of averageArrays in an array which I can then plot. To see the whole frequency range, you would need to sweep freq2 over the whole range.

i've got some time later today, i'll jump in and see what i can do. :)

Thanks! I think I can get the hang of reactive style if I can figure out where to store persistent results. Almost there. Some less-great things that need refactoring, getCosineArray()[0] doesn't change so could be precomputed (how do I set the x axis labels to it though?)

Did some refactoring so things are better. What I want to do now is put the 2 plots above this next to each other, so the red dot tracks the red line. I'm sure there's a better way than <table> lol
