Practice Questions

Test your understanding with targeted questions

Question 1 Easy

Given the arrays A = [1, 2, 3] and B = [4, 5, 6], calculate C = A + B.

💡 Hint: Use element-wise addition.

Question 2 Easy

What is the result of A .* B given the same arrays?

💡 Hint: Multiply each corresponding element.

Question 1

What distinguishes array operations from matrix operations in MATLAB?

They are computed on the entire matrix
They are performed element-wise
They can only use integer numbers

💡 Hint: Think about how individual elements are treated in arrays.

Question 2

True or False: To multiply each element of an array A by a scalar, you can simply use A * scalar.

True
False

💡 Hint: Consider how operators are represented for arrays.

Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given A = [1, 2; 3, 4] and B = [4, 3; 2, 1], explain how you would compute the element-wise average of both matrices.

💡 Hint: Consider how you can build A and B into a single operation.

Challenge 2 Hard

Given a linear system represented by Ax = b where A is a random square matrix generated within MATLAB and b is a defined vector, solve for x and demonstrate using both inv(A) and backslash operator.

💡 Hint: Generate a random matrix and observe the output from both methods.
