Use MATLAB to solve the following exercise Given the matrice

Use MATLAB to solve the following exercise.

Given the matrices:

A = [ -7 16

        4 9 ]

B = [ 6 -5

        12 -2]

C = [ -3 -9 4

        6 8 -5]

a. Find A + B

b. Find A - B

c. Find 2A + 3B

d. Find BC

Solution

a)

A = [ -7 16; 4 9 ]

B = [ 6 -5; 12 -2 ]

C = A + B;

b)

A= [ -7 16; 4 9 ]

B = [ 6 -5; 12 -2 ]

D = A - B;

c)

A= [ -7 16; 4 9 ]

B = [ 6 -5; 12 -2 ]

E = 2A + 3B;

d)

B = [ 6 -5; 12 2 ]

C = [ -3 -9 4; 6 8 -5]

F = B * C;
