error in solving numerical integral

Hi,

I want t slve a Numerical Integral fOr Leonard-johnes Potential

How can I Solve this error ?

Fun=@(x,t)(x^2*(exp(-((1/(x^12))-(1/x^6))/t))-1));
Q=integral(@(x)Fun(x,10),0,2)

Error In integral

I Also need to plot Q in different t

Do You Have Any Comments ?

Answer 1

[madhan ravi]

syms t x % at the very beginning
%remove @(x,t) and replace it with matlabFunction()

Answer 2

[Walter Roberson]

Fun=@(x,t) x.^2.*(exp(-((1./(x.^12))-(1./x.^6))./t))-1

You had too many ) and you needed to vectorize. integral() always invokes the function with a vector of values rather than just a single value.
