MATLAB: Functions handle (product of functions)

quad; integral; product of functions

Dear all, I have the following functions:

X=@(fi) 2*sqrt(5/8)*atan(sqrt(45)*fi.); h=@(fi) 10*fi.^2;

However, I need to calculate the follow function:

f=X*h area= quad(f,0,10)

Can anyone help me? Thanks a lot. Marcus Vinicius

hi,

why dont you use one single function handle :

 >>G=@(fi) 2*sqrt(5/8)*atan(sqrt(45).*fi)*10.*(fi.^2) % This is X*H
 >>I=quad(G,0,10)

Dear Mustafa,

function y = calculate_sqrt(x)
y = x .* (sqrt(x) - sqrt(x - 1));
end

you can save it with the name "calculate_sqrt.m"

and then later you call it as

x = [10 100 1000];
y = calculate_sqrt(x);

I hope it helps. Good luck!

hi , try :

 >>F=@(x) sqrt(x);
 >>I=quad(F,0,10)
