Getting the wrong plot?

function dLdt = Lorentz(t,xyz,s,b,r)

xyz = [3;2;3];

s = 10;

b = 8/3;

r = 0.5;

dx = s*(xyz(2) - xyz(1));

dy = r*xyz(1) - xyz(2) - xyz(1)*xyz(3);

dz = xyz(1)*xyz(2) - b*xyz(3);

dLdt = zeros(3,1);

dLdt(1)=dx;

dLdt(2)=dy;

dLdt(3)=dz;

Then i use this code to call it

[t,xyz]=ode45('Lorentz1',0:0.001:1,[0;0;0]);

plot3(xyz(1),xyz(2),xyz(3));

I'm getting a straight line plot, which it definitely shouldn't be. Is it the way i've defined my initial conditions?

Your function name is "Lorentz", but the function called by ode45 is 'Lorentz1'. Anything wrong here?
