以求解 x + y = 4 方程組為例
x - y = -1         
Example Code

• import numpy as np
• from numpy import linalg as LA
• MatrixA = np.array([[1,1], [1,-1]])
• MatrixB = np.array([4,-1])
• print('\n coefficients of variables are ]n', MatrixA)
• print('\n constent terms are', MatrixB)
• print('\nsoltion of [x, y] is', LA.solve(MatrixA, MatrixB))

Note and Comments

• import numpy as np: 讀入numpy函式庫並命名為np
• from numpy import linalg as LA: 讀取numpy函式庫的線性代數函式庫並命名為LA
• LA.solve(A, B): A爲係數矩陣, B爲常數項矩陣
