## Main Question or Discussion Point

I have two PDE's. One in terms of dz and the other in terms of dt:

[tex]\frac{dI(t,z)}{dz}=aI(t,z) + bI^2(t,z) - cN(t,z)I(t,z)[/tex]

and

[tex]\frac{dN(t,z)}{dt}=dI^2(t,z) - eN(t,z)[/tex]

I know the function:

[tex]I(t)[/tex]

I'd like advice on how to attempt this problem on matlab using the pde function. (Matlab's examples are too complex to follow).
