Create 3x3 Matrix (2–10)

Write a NumPy program to create a 3x3 matrix with values ranging from 2 to 10.

Sample Solution:

Python Code:

# Importing the NumPy library with an alias 'np'
import numpy as np

# Creating a NumPy array 'x' using arange() from 2 to 11 and reshaping it into a 3x3 matrix
x = np.arange(2, 11).reshape(3, 3)

# Printing the resulting 3x3 matrix 'x'
print(x)

Sample Output:

[[ 2  3  4]                                                             
 [ 5  6  7]                                                             
 [ 8  9 10]]

Explanation:

In the above code -

.reshape(3,3): Reshapes the one-dimensional NumPy array into a 3x3 two-dimensional array.

print(x): Prints the 3x3 NumPy array.

• Create a 3x3 matrix with consecutive integers starting at 2 and ending at 10 using arithmetic progression.
• Generate a 3x3 matrix from a range and then replace the center element with the average of its neighbors.
• Construct a matrix with values from 2 to 10 and verify that each row increases by one from the previous element.
• Generate a 3x3 matrix with sequential values and then transpose it to compare row and column order.
