When recreating the function
method1, I encounter an error message: "setting array with a sequence" on the line of code:mat[i, j] = np.exp(-0.5 / sigma**2 * np.dot(vec, vec))Would you like to verify the version of the code to recreate my problem?
Thank you in advance for considering my question,
Haocheng
