hi, Brandon
In this example you have to use function handle ,so what i understand is that you need to see when the two methods are equal. Here is a proposition :
1) You create a function handle :
f=@(x) sqrt(x)./(x+2);
2) You create the the number of spacing elements on which Trapz method wil be evaluated :
n=2.^(1:7); %
3) You initialize the vectors that will contain the numercial intergations :
I1=zeros(1,7);
I2=zeros(1,7);
4) You implement a loop : ! YOU have to complete the two lines
for ii=1:length(n)
x=linspace(1,3,n(ii));
I1(ii)=quad(f,...... % INCOMPLETE LINE
I2(ii)=trapz(x,..... % INCOMPLETE LINE
end
Now you can see when the two methods are equal .
figure, plot(n,I1); hold on, plot(n,I2,'r'),legend('QUAD','TRAPZ')
