Polyfit 2d python

WebInterpolation (. scipy.interpolate. ) #. There are several general facilities available in SciPy for interpolation and smoothing for data in 1, 2, and higher dimensions. The choice of a specific interpolation routine depends on the data: whether it is one-dimensional, is given on a structured grid, or is unstructured. WebIo uso semplice polyfit di ordine 2 per adattarsi una linea di dati di esempio:Trova incertezza da polyfit. np.polyfit(x, y, 2) che restituisce i coefficienti. Ora voglio trovare l'incertezza della retta, e ha cercato di usare cov argomento, che restituisce matrice 3x3 di covarianza:. np.polyfit(x, y, 2, cov=True)
