Witryna17 mar 2024 · You simply need to pass in a list array as an initial guess to your function. For the second question, if you want to optimize across the full set rather than just single pair of x / y, you should pass these whole arrays in as arguments to the optimize routine. So if you wanted to fit say y = exp ( β x + α), you could do something like Witryna>>> import numpy as np >>> from scipy.optimize import rosen >>> X = 0.1 * np.arange(10) >>> rosen(X) 76.56 For higher-dimensional input rosen broadcasts. In the following example, we use this to plot a 2D landscape. Note that rosen_hess does not broadcast in this manner.
