How to solve a differential equation with time delay using ode45

I am trying to solve follwing differential equation:

A, B and C are constants.

I already tried to solve this equation using ode45 by replacing () by only t. How can I implement the time shift into the code?

y0 = [0];
%theta = 5;
tspan = linspace(0,100,101);
[t,y] = ode45(@(t,y) ((A* (C - y *t).^(B)) - y), tspan, y0);

The equation that I want to solve is

[t,y] = ode45(@(t,y) ((A* (C - y(t-theta) *t).^(B)) - y), tspan, y0);

Thanks

Kind regards
