14:440:127 Introduction to Computers for Engineers Recitation 3- Problems for students to attempt Please complete these problems on your own time if you do not finish in recitation. You don’t need to show us the completed recitation problems, although we recommending saving a copy of your solutions for your own benefit. 1) Create a row vector containing the even numbers 2 through 18, a column vector containing 1,5,9,…,25,29, and a 3*3 matrix A. Then, transpose A and save that as B . Finally, calculate the element by element (dot) multiplication of A and B . 2) Write a program that ask the user to input the value of ‘How many days do you want rent this DVD?’ Then, calculate how much they should be charged for this rental. The store charges $3.99 for the first day, and then $1 for each additional day. However, a week long rental is only $8. After one week, they are charged $1 for each additional day, up to a maximum fee of $50. 3) Create a 3 x 4 matrix in which all the elements have a value of pi. (consider creating a matrix in which all of the values are 1 first, and then multiplying). Then, change the 2nd row to -pi. Finally, compute the sine of each value in the matrix. 4) Find the zeros of the polynomial 5x 4 - 4x 2 + 18 5) Use help to look up the magic function. Create a 5 x 5 magic matrix. Then: a. sort each column of the matrix b. sort each row of the matrix
