running into issues when using Ode 45

Im having issue running this code to find the tt and y values

'Time step'
t = (0:0.01:100);
'loop through these cases of r'
r = [0.05 0.1 0.5 1 10];
'Equation variable'
k = 15
'inital guess'
B(0) = 1

'Equation'
dBdt = @(r,k) (r * B)*(1-(B/k));

'for loop to loop through the cases in r'
for i = 1: length(r)
[tt,y] = ode45(dBdt(i),t,1)
end

Can you post the differential equation you are trying to solve?
