i am trying to Numerical integration by following this example
"Create the function f(x) = e-x2(ln x)2. fun = @(x) exp(-x.^2).*log(x).^2; Evaluate the integral from x=0 to x=Inf. q=integral(fun,0,Inf) "
but i am getting "too many input arguments" error message.
kindly help me to solve this problem
Regards

Thanks for your help. Its means that integral function is only available in matlab 2012 and above versions.

My guess is that somewhere in your code you have defined another function and given it the name 'integral'. Matlab is confused by the conflict of names.

What does "which -all integral" display? [Don't include the quotes when you type that command at the MATLAB prompt.]
