Simulating a integral equation in matlab

Hi guys,

I am trying to write a equation by using simulation but I don't know how can I simulate the equation with integral. I know how to solve a first and second order differential equation in matlab but this is not a differential equation! what should I do?

the equation is:
Thanks

What variable are you solving for? What do you know about the other functions? Are you looking for a symbolic solution or a numerical solution?
