Problem in ezplot with simple equation

s=dsolve ('Dy=(t+y)^(1/2)','y(0.4)=0.41')

ezplot(s,[0.4,10])

Whats wrong???

Not all differential equations have analytical solutions. Fortunately, ode45 will integrate this without problems:

DE = @(t,y) (t+y)^(1/2);
[T,Y]= ode45(DE, [0.4 10], 0.41);

figure(1)
plot(T,Y)
grid

As always, my pleasure.
