Question

In Matlab write a script that does the following. 1. Creates a row vector v = [3, 6, 9, 9, 15], and then manipulates v to create each of the following vectors (and then displays the result of each): (a) a = [9, 36, 81, 81, 225] (b) b = [ 1 3 , 1 6 , 1 9 , 1 9 , 1 15 ] (c) c = [1, 2, 3, 3, 5] (d) d = [15, 9, 9, 6, 3] 2. Creates a vector w that contains values from zero to 10 (with a spacing of 2 in between values), and then multiplies the entire array by 3, then subtracts 10 from every element, and stores the result in a vector z (and displays vector z). 3. Creates the following arrays: A = 1 2 3 −2 0 1 0 7 2 B = 1 2 3 −6 10 1 2 0 5 C = 0 3 1 −2 0 1 D = 0 0 0 0 0 1 And then calculates each of the following (and displays the result): • The matrix product of A and B • The matrix product of B and A • The result of multiplying A and B element-by-element • The inverse of A • A single boolean (1 or 0), indicating whether or not A contains the number 7 • A single boolean (1 or 0), indicating whether or not D is ALL zeros • A single boolean (1 or 0), indicating whether or not A and C are equal • A single boolean (1 or 0), indicating whether or not A and B are equal • An ARRAY of booleans, indicating whether EACH ELEMENT of A matches the corresponding element of B • The sum of ALL of the elements in C
