To create a graph illustrating a gradient vector using Python, you can follow these steps:
import numpy as np
import matplotlib.pyplot as plt
def f(x, y):
return x**2 + y**2
meshgrid
function.x = np.linspace(-5, 5, 10)
y = np.linspace(-5, 5, 10)
X, Y = np.meshgrid(x, y)
gradient
function.gx, gy = np.gradient(f(X, Y))
quiver
function. This plots arrows that represent the direction and magnitude of the gradient vector.fig, ax = plt.subplots()
ax.quiver(X, Y, -gx, -gy)
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_title('Gradient Vector')
plt.show()
The resulting plot will show arrows indicating the direction and magnitude of the gradient vector at different points on the function's surface.
