%list of the constants we are going to need. Note, all of these are the 
rm=2300; %units: ohms * centimeters
cm=1; %units microfarads/centimeter
rl=60; %units 60 ohms/centimeter
%a=10^-3; %units in centimeters

%m=0;
%xmesh=linspace(0,1,20);
%timespan=linspace(0,1,100);

%figuring out the space and time constant
lambda=sqrt(rm/rl);
tau=rm*cm;
Vlambda=0.368*Vo;

c=lambda.^2;
f=tau*deltav;
s=Vlambda;


function u=icfun(x) %x is merely a placeholder until we get v.
u=sin(pi*x);

function [pl,ql,pr,qr]=bcfun(xl,ul,xr,ur,t)
pl=ul;
ql=0;
pr=lambda*exp(-t);
qr=1;
