Hi all,
Everyone can tell me how to make the output of an integral function as a function, please? I try the following code, but the result is wrong.
>> f0=@(x) x^2;
>> f1=@(x) (x*quad(@(x) f0,0,2));
>> f0(4)
ans =
16 (>>>>> *good result*)
>> f1(4)
Warning: Maximum function count exceeded; singularity likely. > In quad at 106 In @(x)(x*quad(@(x)f0,0,2))
ans =
57.1751 (>>>>>> *bad result*)
Thank you in advance for your help!!!

Thank you so much for your prompt answer. But Matlab shows me the error:
??? Error using ==> mpower Inputs must be a scalar and a square matrix.
Error in ==> @(x)x^2
Error in ==> quad at 77 y = f(x, varargin{:});
Error in ==> @(x)(x*quad(f0,0,2))
Do you have another idea? Thanks you!

Thank Walter Roberson! I have a right result now. Hope that works with triple integral (triplequad). I would like to accept your answer, but this button is no longer appeared when I make my comment. Sorry!
