scipy How to write a Jacobian function for optimize.minimize Optimization Example (golden)
Example
The 'Golden' method minimizes a unimodal function by narrowing the range in the extreme values
import numpy as np
from scipy.optimize import _minimize
from scipy import special
import matplotlib.pyplot as plt
x = np.linspace(0, 10, 500)
y = special.j0(x)
optimize.minimize_scalar(special.j0, method='golden')
plt.plot(x, y)
plt.show()
Resulting image
