Matlab-linear algebra problem please help! I will give a thumb up, thank you!

There is no other information or detail about this question, so I am confuse now.

In this problem you will write two Matlab functions to compute the matrix-vector product of an n n matrix A and a length n column-vector x. In a later assignment, we will use these functions to investigate how the order in which the data is accessed in a matrix computation can dramatically affect the performance of the algorithm. Note that you can easily check the result of your functions by computing directly the product A*x and comparing the results. For this problem vou should hand in a print-out of vour functions i. Write a function called axrow that takes as arguments an integer dimension n, an n n matrix A, and a length n vector x and returns the result of computing the matrix-vector product b - Ax by the row-vector rule. Use vector operations only (that is, do not access elements of A or x individually). The value b returned by your function should be a column vector. ii. Write a function called axcol that takes as arguments an integer dimension n, an n n matrix A, and a length n vector x and returns the result of computing the matrix-vector product b- Ax by taking a linear combination of the columns of A. Use vector operations wherever possible. The value b returned by your function should be a column vector In this problem you will write two Matlab functions to compute the matrix-vector product of an n n matrix A and a length n column-vector x.
