![Problem 4: If you have two matrices, A and B, and the MATLAB outputs of size (A) and size(B) are [3 2] and [2 4], respectively, what is the output of size(A*B)? What is the output of size(B*A)? Explain why the outputs are what they are. Problem 5: If you have two vectors a[1 2 3 4] and b -[2 3 4 5], what is the output of a*b? What is the output of a.*b? Explain why the outputs are what they are. Problem 6: Ifyou have two matrices, A [1 2 3; 4 5 6; 7 8 9] and Bones (3) what is the output of A*B? What is the output of A.*B? Explain why the 2 EGM 3344 INTRODUCTION TO NUMERICAL METHODS OF ENGINEERING ANALYSIS outputs are what they are.](http://img.homeworklib.com/questions/439b3210-637d-11eb-a2dc-6de4c32592d1.png?x-oss-process=image/resize,w_560)
Problem 4 I need all of it, the other two I just need the explanations at the ends.
Homework Answers
To find AB, we must be sure to find the dot product between each row in A and each column in B. So, the resulting matrix will have the same number of rows as matrix A3×2?, and the same number of columns as matrix B2×4 so the resulting matrix will be of size[3,4] in case of AB
in case of BA the multiplication wont be possible as number of columns in B != number of rows in A.
