Accessing Value in a matrix
Method 1: Accessing Matrix values
Here, we are accessing elements of a Matrix by passing its row and column.
Python3
print("Matrix at 1 row and 3 column=", X[0][2]) print("Matrix at 3 row and 3 column=", X[2][2]) |
Output:
Matrix at 1 row and 3 column= 3 Matrix at 3 row and 3 column= 9
Method 2: Accessing Matrix values using negative indexing
Here, we are accessing elements of a Matrix by passing its row and column on negative indexing.
Python3
import numpy as npX = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]print(X[-1][-2]) |
Output:
8
