Challenge Problems

Push your limits with challenges.

Question 1

Create a 4x4 matrix filled with random integers from 1 to 10 and then extract the last two rows and last two columns.

πŸ’‘ Hint: Use the randi function to generate your matrix.

Question 2

Given a matrix A = [2 7 1; 3 5 8; 9 4 6], delete the first row and then create a sub-matrix with the remaining rows and columns 1 and 3.

πŸ’‘ Hint: Remember, deleting a row affects the indexing of your sub-matrix.
