function ped1
sol =pdepe(m,@pdefun,@pdeic,@pdebc,xmesh,tspan);
u=sol(:,:,1);
function [c,f,s]= pdefun(x,t,u,DuDx)
c = V/D;
f = DuDx;
s=0;
end
ped1
Undefined function or variable 'V'.
Error in pdefun (line 2)
c = V/D;
Error in pdepe (line 246)
[c,f,s] = feval(pde,xi(1),t(1),U,Ux,varargin{:});
Error in ped1 (line 27)
sol =pdepe(m,@pdefun,@pdeic,@pdebc,xmesh,tspan);

"in pdefun; is that possible to use array for the term "c" nstead of constant?"
MATLAB does not have any "constant" class, so it is not clear what you mean. Perhaps you mean that c is scalar?
In any case, the pdepe help states the the first output c should be a column vector. Given that both V and D are scalars, it is not clear what you expect c to be. Please show an example.
