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

In summary, Matlab is a high-level programming language and interactive environment used for numerical computation, data analysis, and visualization. It can handle systems of equations with multiple variables and provides accurate solutions. However, it may struggle with very large systems and non-linear equations. Additionally, Matlab allows for visualizing the solutions of a system of equations through its built-in graphing functions.

I have function:

Code:
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??

It is ok, work.

I greet.
