Plotting a result from dsolve

Hi, I'd like to add a plotting command for the result of

syms h g 
h = 1
g = 4
dsolve('h^2*(D2v)+2*i*g*h*Dv-g^2=0','v(0)=x')

How can this be done?

Thanks

I am not sure what x is in this case, but you should be able to use fplot or fplot3 to plot the function. You may need to constrain it some more to eliminate the constant terms or define what x should be, but those are the functions that can take the output of dsolve and plot it. I have made a little example below based on the dsolve documentation example.

syms y(t) a b; 
a = 1; b = 4;
eqn = diff(y,t,2) == a^2*y;
Dy = diff(y,t);
cond = [y(0)==b, Dy(0)==1];
ySol(t) = dsolve(eqn,cond);
fplot(ySol);

Is it possible to put the condition latter? How to plot in that case.
