Nettet30. jan. 2024 · The very first step of the algorithm is to take every data point as a separate cluster. If there are N data points, the number of clusters will be N. The next step of this algorithm is to take the two closest data points or clusters and merge them to form a bigger cluster. The total number of clusters becomes N-1. Nettet9. nov. 2014 · def integrate (f, a, b, N): x = np.linspace (a, b, N) fx = f (x) area = np.sum (fx)* (b-a)/N return area We can now use the function to integrate a sine curve between 0 and and pi/2. This should produce 1. Let’s run it using 100 steps. integrate (np.sin, 0, np.pi/2, 100) This gives: 0.99783321217729803 The answer is off by about 0.002.
