Question

3. Assume that a = 3; b = 2; c= 5; d = 3; Evaluate the following MATLAB assignment statements: (a) output = a*b+c+d; (b) output = a*(b+c)*d; (c) output = (a*b)+(c d): (d) output = a b d: (e) output = a (b^d):

Answer 1

To evaluate the given statements, we just initialize the variables a,b,c & d to given values and then execute each statement in the MATLAB command window. After each execution, we can see the value stored in the output variable using the disp command. So the screenshots showing answer to each part are shown below:

a)

>> a = 3; b = 2; >> c = 5; d = 3; >> output = a*b+c*d; >> disp (output) 21

Answer: 21

b)

>> output = a* (b+c) *d; >> disp (output) 63

output = 63

c)

>> output = (a*b)+(c*d); >> disp (output) 21

output = 21

d)

>> output = a^b^d; >>> disp (output) 729

output = 729

e)

>> output = a* (bºd); >> disp (output) 6561

output = 6561
