2. Use vectors in scalar calculations.

Write single MATLAB statements to perform these operations on vectors, use calculator mode and save your code and results to a diary file. Use this vector in the following exercises: x = [0 3 -4 4.5]; Do not change vector x, let all the results go to the default "ans" identifier. One of them produces an error.

A. Subtract 7 from every element of x B. Add .5 to every element of x

C. Multiply every element of x by 2 D. Subtract x from 5 E. Divide 4 by x F. Divide every element of x by -3

3. Accessing vector elements for calculations.

Write single MATLAB statements to perform these operations on vectors, use calculator mode and save your code and results to a diary file. Do not change vector x, let all the results go to the default "ans" identifier.

A. Using the vector x from problem number 2, use the disp() function to display the third element of x. B. Using the vector x from problem number 2, add 10 to the second element of x. C. Sum all the elements of the vector C from problem 1C.

D. Display the last element of the vector E from problem 1E (assume you do not know how many elements are in E).
