Question

If someone could explain and help me fix the part that show as

ans = 16

I dont get why that shows up and i have check the program already

19 grade = input ('Error! Enter a valid grade: "); end fprintf("The valid grade enteres is: $1f\n', grade) $ Question 3 El function (arovo] - rectareavol (length, width, height) if nargin = 2 fif arguments is equal to A = length*width; then area is length*width arovo = fprintf("The Area is: d',A); else A =length*width; V =length*width*height; Sif height is also given arovo = fprintf ("The Area is [ld] and the Volumen is [d] , end then calculates the volume end 88 Question 4 for i=1:20 fprintf('%d', fibonacci(i-1)) -end function [E] = fibonacci (n) Command Window >> rectareavol (2,2) The Area is [4] ans = o xw SP ^ a 4) ENG 2020-C

Answer 1

Note: Please put ; after function call to avoid getting ans = 16;

=================== modified matlab code =========================

%%%%% question 3%%%%%%%%%%
function [arovo] = rectareavol(length,width,height)
if nargin == 2
A = length * width;
arovo = fprintf('The area is [%d]\n',A);
else
A = length * width;
V = length * width * height;
arovo = fprintf('The Area is [%d] and the Volume is [%d]\n',A,V);
end
end

>> [arovo] = rectareavol (2,2); The area is [4]
