Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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

💡 Hint: Use the randi function to generate your matrix.

Challenge 2 Hard

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.

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