What is Causing an Error in My Matlab Code for Solving a System of Equations?

[dexter90]

I have function:

function dxdy = kkd(t,y)
x=y(1);
y=y(2);
dxdy(1)=-0.02*x+x*x*y+0.01;
dxdy(2)=0.02*x-x*x*y;

next

[t,y]=ode45(@kkd,[0 4],[0 10]);

but is error... Where is error??

 

[Dr Transport]

you never set the initial conditions, what is y(1) and y(2)?

It is ok, work.

I greet.
