1. Scalar Variables: Make the following variables

a. a = 10;

b. b = 2.5 1023

c. c = 2+3i, where i is the square root of -1

d. d = e j2/3 , where j is the square root of -1 and e is Eulers number (use exp, pi)

2. Vector Variables: Make the following variables

a. aVec = [3.14 15 9 26]

b. bVec = [ 2.71

8

28

182]

c. cVec = [5 4.8 -4.8 -5] (all the numbers from 5 to -5 in increments of -0.2)

d. dVec = [100 100.01 100.99 101 ] (Logarithmically spaced numbers between 1 and 10, use logspace, make sure you get the length right)

3. Matrix Variables: Make the following variables

a. Create a 9 x 9 matrix full of 2s (use ones command)

aMat = [ 2 2 2 2 2 2 2 2 2

2 2 2 2 2 2 2 2 2

2 2 2 2 2 2 2 2 2

2 2 2 2 2 2 2 2 2

2 2 2 2 2 2 2 2 2]

b. Create a 9 x 9 matrix full of 3s (using zeros command)

c. Create a 9 x 9 matrix of all zeros but with the values [1 2 3 4 5 6 7 8 9] on the main diagonal (use zeros, diag)

cMat = [ 1
