hi,
this is my program but i don't find where is the error plz help me it's urgent. thanks for your help in advance.
function pdex
m = 0;
z = linspace(0,100,100);
t = linspace(0,5,5);
sol = pdepe(m,@pdexpde,@pdexic,@pdexbc,z,t);
C = sol(:,:,1);
figure;
plot(z,C(end,:));
% ----------------------------------------------------------
function [g,f,s] = pdexpde(z,t,C,DCDz);
rhos=0.55;
rhof=0.385;
epsilon=0.64;
u=0.05;
keq=23.53;
A=1+(((1-epsilon)/epsilon)*keq*(rhos/rhof));
B=u/epsilon;
g=A;
f=0;
s=(-B)*DCDz;
% ----------------------------------------------------------
function C0 = pdexic(z);
a=0.0015;
C0=a;
% ----------------------------------------------------------
function [pl,ql,pr,qr] = pdexbc(zl,Cl,zr,Cr,t)
pl = 0;
ql = 0;
pr = 0;
qr = 1;

Do we get a hint about what error you observe? An error message and an associated line?

If your question is any kind or "urgent", it would be a very good idea to explain anything about the problem.
