Write a function named myrowproduct that takes in input a matrix a column vector and a random number and as output gives the product computed by row as defined above, and the intermediate value, of the output vector at the end of iterations this intermediate value is used by MATLAB Grader to determine whether your code is correct
Specific instructions for writing the function:
Extract the dimension of A using the command size and store the result in the variables and
Extract the dimension of using the command size and store the result in the variables and
Use an if statement to perform a check on the dimensions to determine whether the multiplication is defined and whether is a column vector
If the multiplication is defined and is a column vector:
initialize the vector as a vector of zeros of the appropriate dimension
use a single for loop to evaluate the entries of the product The loop counter should be the variable i Each iteration of the for loop should evaluate the ith component of the vector as the product of the ith row of A times the vector Also, inside the for loop, after you compute the ith component of insert the following commands:
