NumPy: Add a vector to each row of a given matrix
NumPy: Basic Exercise-34 with Solution
Write a NumPy program to add a vector to each row of a given matrix.
Sample Solution :
Python Code :
import numpy as np m = np.array([[1,2,3], [4,5,6], [7,8,9], [10, 11, 12]]) v = np.array([1, 1, 0]) print("Original vector:") print(v) print("Original matrix:") print(m) result = np.empty_like(m) for i in range(4): result[i, :] = m[i, :] + v print("\nAfter adding the vector v to each row of the matrix m:") print(result)
Original vector: [1 1 0] Original matrix: [[ 1 2 3] [ 4 5 6] [ 7 8 9] [10 11 12]] After adding the vector v to each row of the matrix m: [[ 2 3 3] [ 5 6 6] [ 8 9 9] [11 12 12]]
