I want to solve a system of 2 coupled pde (in MATLAB) of the format:(adsbygoogle = window.adsbygoogle || []).push({});

c1*(df/dt)+c2*(df/dz)+c3*(f)+c4*(g)=0

(dg/dt)=c5*f+c6*g

with Initial conditions as

f(0,t)=1, g(z,0)=0 and f(z,0)=0

0<f,g,z,t<1

I tried using the MATLAB function pdepe to do this but got errors and if I go for numerical solving by finite difference method I get the value of f>1 which is not possible.

Please help me with this problem!
