How do i plot a derivative versus time

I have the code below and want to plot for eg yp(2) vs time-

How can I do this?

function yp = reduced(t,y) 
m_a = 0.5; 
c_ay=1; 
c_az=1; 
k_ay= 1; 
k_az =1; 
Fy=@(t)1; 
Fz=@(t)1; 
T_a = @(t)178; 
I_a = 2000; 
R_a=1; 
yp = zeros(6,1); 
yp(1) = y(2); 
yp(2) = (-Fy(t) - k_ay*y(1) - c_ay*y(2))/m_a; 
yp(3) = y(4); 
yp(4) = (-Fz(t) - k_az*y(3) - c_az*y(4))/m_a; 
yp(5) = y(6); 
yp(6) = (-T_a(t) - Fy(t)*R_a)/I_a; 
end

[T,Y] = ode45(@reduced,tspan,y0)
for i = 1:numel(T)
  dy(i,:) = reduced(T(i),Y(i,:));
end
plot(T,dy(:,2))

Thanks. I tried this, but I am getting errors

tspan = [0 10]; 
y0 = zeros(6,1); 
[T,Y] = ode45(@reduced,tspan,y0) 
for i = 1:numel(T) 
    dy(i,:) = reduced(T(i),Y(i,:)); 
end 
plot(T,dy(:,2))

Runs without problems.

tspan = [0 10];
y0 = zeros(6,1);
[T,Y] = ode45(@reduced,tspan,y0);
for i = 1:numel(T) 
    dy(i,:) = reduced(T(i),Y(i,:)); 
end 
plot(T,dy(:,2)) 

function yp = reduced(t,y) 
m_a = 0.5; 
c_ay=1; 
c_az=1; 
k_ay= 1; 
k_az =1; 
Fy=@(t)1; 
Fz=@(t)1; 
T_a = @(t)178; 
I_a = 2000; 
R_a=1; 
yp = zeros(6,1); 
yp(1) = y(2); 
yp(2) = (-Fy(t) - k_ay*y(1) - c_ay*y(2))/m_a; 
yp(3) = y(4); 
yp(4) = (-Fz(t) - k_az*y(3) - c_az*y(4))/m_a; 
yp(5) = y(6); 
yp(6) = (-T_a(t) - Fy(t)*R_a)/I_a; 
end

sorry, it was my fault. Thanks once again!
