$$A = \begin{pmatrix} a & b \\ c & d \end{pmatrix}, \qquad \det(A) = ad - bc$$

Code

import numpy as np
 
def gaussian(x: np.ndarray, mu: float = 0, sigma: float = 1) -> np.ndarray:
    return np.exp(-0.5 * ((x - mu) / sigma) ** 2) / (sigma * np.sqrt(2 * np.pi))

const greet = (name: string): string => `Hello, ${name}!`;
console.log(greet("Yuxin"));
