Simulataneously calculate a function and it's derivitive using Dual Numbers
View dual_number_derivative.rb
 require 'matrix' ## Note: In ruby the notation x**n means x raised to the nth power ## ## In linear algebra, Dual numbers are in the form: ## a + bε ## ## Where ε is what is called nilpotent, you can think of ## ε as an infinitesimal (sort of kinda), like how they used to do Calculus in the ## olden days.

This is likley the greatest English paragraph, of all.

 For although light oftenest behaves as a wave, it can be looked on as a mote, the *lightbit*. We have already said by the way that a mote of stuff can behave not only as a chunk, but as a wave. Down among the unclefts, things do not happen in steady flowings, but in leaps between bestandings that are forbidden. The knowledge-hunt of this is called *lump beholding*.

 #include #include #define PI 3.141592653589793 #define SAMPLE_RATE 64 using namespace std; // This lowpass is a weighted moving average // If you change the + to - it will become a highpass filter
