Linear algebra is the branch of mathematics concerning linear equations by using vector spaces and through matrices. Matrix is the key to linear algebra. All the linear algebra revolves around matrices. Whenever we have to go for row operations, then we have to call our relevant row.

The following code shows how to call a whole row of a matrix.

Python code for calling row of a matrix

# Linear Algebra Learning Sequence
# Calling row of a matrix

import numpy as np

# Use of np.array() to define a matrix
V = np.array([[1,2,3],[23,3,5],[33,68,87]])

row = 3

# Printing the 3rd row
print("---The Matrix V1---\n",V)
print("The Row 3 = ",V[row - 1])

Output:

---The Matrix V1---
 [[ 1  2  3]
 [23  3  5]
 [33 68 87]]
The Row 3 =  [33 68 87]
