How can I create a random input similar to "band-limited white noise", but in an m-file in an ODE to solve with ode45?

I would like to write an m-file in which an ordinary differential equation is defined.
I have to add a gaussian white noise to that. I have created a file in Simulink for that, but I am not able to write similar code.

Actually, "randn()" is better and creates numbers with normal distribution, but the variance of the output of the ODE would not match Simulink.
