Exercise 557
Consider the following matrix: A = np.array ([[3, -1], [-1, 4], [7,11]]) Give the Python code numpy which displays the rows of the matrix as follows:
line number 1 is: [3 -1]
line number 2 is: [-1 4]
line number 3 is: [7 11]
Solution
import numpy as np
A = np.array([[3, -1],
[-1 , 4],
[7,11]])
B = np.append(A , [[1 , 1]])
i = 1
for x in A:
print("ligne number ", i , " is : " , x)
i = i + 1
