NumPy 中可以使用np.linalg.solve(a, b)函数解线性方程组Ax = b。 matrix_a_equations = np.array([[2, 1], [1, -1]]) # 系数矩阵 A vector_b_equations = np.array([8, 1]) # 常数向量 b # 解线性方程组 Ax = b vector_x_solution = np.linalg.solve(matrix_a_equations, vector_b_eq...
b=np.array([8,18]) print(("Solution of linear equations:", np.linalg.solve(a,b))) 1.
The numpy linalg.solve function is a very useful function that takes care of the tedious matrix calculations for you. It is used to solve linear equations and find out the unknown variable or a system of linear scalar equations. It is based on the same condition that we discussed above: AC...
