Solving differential equation using ode45 in a single file

Hello

I need to solve the following ODE using ode45 function:

dy/dx=(y/x)-(y/x)^2, in interval 1<=x<=2, and initial condition of y(1)=1

I am struggling with creating a script in a single file without using a separate function file. I thought this would work but it gives an error:

[x,y]=ode45(@deriv, [1,2],1);
function dydx=deriv(x,y)
dydx=(y/x)-(y/x)^2

Any help would be appreciated.

Thanks

   [x, y] = ode45(@(x,y) (y./x)-(y./x).^2, [1, 2], 1);

Thank you Walter. Much appreciated. I'll try it out when my new MATLAB license gets in
