Differential equations using ODE45

please help me in solving this question..

Q. solve:

dy1/dt = y2

dy2/dt = 1000*y2*(1-y1^2)-y1

given initial conditions : y1(0) = 0 and y2(0) = 1.

Answer 2

[Md Muzakkir Quamar]

tspan = [0 20];

Y_int=[0 1];

[t,x] = ode45(@odefcn,tspan,Y_int,[],a, b, c, u);

figure(1)

plot(t,y(:,1),'r',t,y(:,2),'b')

function dydt = odefcn(t,y)

dydt = zeros(2,1);

dydt(1) = y(2);

dydt(2) = 1000*y(2)*(1-y(1)^2)-y(1);

end

Please don't post the full answers to questions that sound like homework assignments, particularly if the poster has not shown what they've tried first.
