I ma trying to do Numerical Integration but getting an error

 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

Please post the failing code. How could we suggest an improvement without seeing it?

[noaman naseer]

actually it is an example available on mathworks http://www.mathworks.com/help/matlab/ref/integral.html

[Torsten]

Use quad instead of integral:

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.

yes you are right. But now i have different type of error

[Steven Lord]

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