how to solve pde

function [j,f,s] = pde1(z,t,c,dcdz,C)

D = 0.01;

e= 0.6;

F=1-e/e;

H=2;0;

u=0.05;

j = 1;

f = (D/(1+(F*H)))*dcdz;

s = -(u/(1+(F*H)))*dcdz;

end

function c0=pde1IC(z)

c0=10;

end

function [pl,ql,pr,qr]=pde1BC(zl, cl,zr,cr,t)

pl=c;

ql=0;

pr=c-10;

qr=0;

end

at command window

z=linspace(0,10,100)

t=linspace(0,200,2000)

m = 0;

eqn = @(z,t,c,dcdz) pde1PDE(z,t,c,dcdz,C);

sol = pdepe(m,eqn,@pde1IC,@pde1BC,z,t);

but the command window display:

pde1IC' is an unrecognized function or variable. Error occurred: pdepe (line 229) temp = feval(ic,xmesh(1),varargin{:});

What can I do .....

Getting the same error! driving me nuts
