Functions handle (product of functions)

1 次查看（过去 30 天）

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

i am not sure if we can define function based on functions but as alternative solution take a look at the solution below

Thanks a lot!! Best wishes, 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)
