Question A 12 

Write the matrix A that would result from the following lines of MATLAB code:
A = zeros(2,3); 
Make sure you understand the problem fully: What is the question asking you to do? Are there specific conditions or constraints that you should take note of? How will you know if your answer is correct from your work only? Can you rephrase the question in your own words in a way that makes sense to you? 
If you are stuck, check the hint below. Consider it for a while. Does it give you a new idea on how to approach the problem? If so, try it! 
Hint 

What is the dimension of A? All entries of A are initially zero. Which entries are then changed in line 2 and 3? 
Checking a solution serves two purposes: helping you if, after having used the hint, you still are stuck on the problem; or if you have solved the problem and would like to check your work.

Please rate my easiness! It's quick and helps everyone guide their studies. These commands have the following effects, in sequence: "A = zeros(2,3);" creates a matrix of zeroes having 2 rows and 3 columns. "A(1,1) = 2;" changes the value in the first row, first column entry to 2. "A(2,3) = 3;" changes the value in the second row, third column entry to 3. The result is the following matrix, "A".
