draw orthogonal trajectories of differential equation

equation is

dy/dx = -d*x/e*y

syms y(x)

a=2;

b=3;

c=5;

d= 5;

e = 8;

ode = diff(y,x) == (-d*x)/(e*y);

ysol = vpa(dsolve(ode));

ezplot(ysol(1))

hold on

ezplot(ysol(2))

ezplot(ysol(3))

getting this error

index exceeds matrix dimensions.
