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.

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.
