Instructions: For the following exercise and the output obtained by running the and into a text document the function M-files 4. The product y = Ax of an m × n matrix A times a vector x = (r , zn)T can be computed 2, w-ise as that is Write a function M-file that takes as input matrix A and n vector x, and as output gives the product yAx by rou, as defined above (Hint: use a for loop to define each entry of the vector Your M-file should perform a check on the dimensions of the input variables A and x and return a message if the dimensions do not match. Cal the file nyrowproduct.m. Note that this file will NOT be the same as the myproduct.m M-file example. Test your function on n random 2 × 3 matrix A and random 3 × 1 vector x. Compare the output with Aex Repeat with 3 × 4 matrix and a 4 x 1 vector ard with 3 × 4 matrix ard a 1 × 4 vector Include in your lab report the function M-file and the output obtained by running it 5. Recall that if A is an m × n matrix and B is a p x q matrix, then the product C = AB is defined if and only if = p, in which case C is an m × q matrix. (a) Write a function M-file that takes as input two matrices A and B, and as output produces the product by colmns of the two matrix For instance, if A is 3 × 4·and B is 4 × 5, the product is given by the matrix The function file should work for any dimension of A and B and it should perforn a check to see if the dimensions match (Hint: use a for loop to define the columns of C). Call the fle col unnproduct·n. Test your function on a random 2 × 3 matrix A and a random 3 x 2 matrix B . Compare the output with A*B. Repeat with 3 x 4 and 4 x 2 matrices and with 3 4 and 2 × 4 matrices. Include in yur lab report the function M-ile and the output obtained by running it (b) Write a function M-file that takes as input two matrices A and B, and as output produces the product by rows of the two matrices For instance, if A is 3 × 4 and B is 4 × 5, the product AB is given by the matrix The function file should work for any dimension of A and B and it should perform a check to see if the dimensions match (Hint: use /1 for loop to define the rows of C). Call the file rowproduct.m Test your function on a random 2 × 3 matrix A and a ranolom 3 x 2 matrix B . Compare the output with A*B. Repeat with 3 × 4 and 4 × 2 matrices and with 3 × 4 and 2 × 4 matrices. Include in your lab report the function M-file and the output obtained by running it
