Subject: Differential equation and ode45 or ode15i

dq/dz=dy/dz+q  
dy/dz=z*y
ds/dz=dy/dz+dq/dz

y=10, dy/dz=0 for z=0
z=15, dz/dz=0 for z=0
q=11, dq/dz=0 for z=0


1- how can solve this problem ? using ode45 or ode15i


if i need to use ode45 can make like this

dy(1)=dy(2)+y(1)
dy(2)=y(2)*z
dy(3)=dy(2)+dy(1)


as a function filw ?

Thanks
