2 Vectors

Open and edit the script q2.m provided to you to answer the parts of this question.

Note that the script makes a vector named v for parts (d)–(f) of this question; you must not delete, comment out, or change the vector v.

(a) [1 mark]

Make a row vector named r1 having values 1, 10, 100, 1000.

(b) [1 mark]

Using the colon operator, make a row vector named r2 having values 1, 11, 21, 31, 41.

(c) [1 mark]

Using the linspace function, make a row vector named r3 having values 0, 10, 20, 30, 40, 50.

(d) [1 mark]

For parts (d)-(f) the vector v has a random number of elements and random element values; each time this script is run, the vector v will change. Your answers should work every time this script is run.

Make a variable third that has a value equal to the third element of v.

(e) [1 mark]

Make a variable thirdLast that has a value equal to the third last element of v.

(f) [3 marks]

Note that v always has an even number of elements.

Make a vector w that is equal to the last half of the elements from v followed by the first half of the elements from v; for example, if v is equal to the vector [1 2 3 4 5 6] then w should be equal to the vector [4 5 6 1 2 3].
