First of all, your file does not have a valid MATLAB script name because it has spaces and parantheses in it. I removed them, but please rename it or you won't be able to run it.
Further, you have defined X and T as
when you probably want
X = 0:0.001:1;
T = 0:0.1:500;
X = linspace(0,1,1001);
T = linspace(0,500,5001);
Also, you had an error in the 3D plot function surf because your third input (ur) is supposed to vary over both the first (X) and the second inputs (T), and therefore necessarily need to be a 2-D matrix. In your case, ur seems to only vary with X.

Hi Iman,
As the ARK mentioned in the comment, the file does not have valid MATLAB script name.I tried to run the code I am getting the following error:
Error using conturningRE (line 15)
mu should<1.0!
Also, for the communtity members it is difficult to debug large code ,so It would be helpful for us if you specify where you are having trouble and what error are you getting.
Let us know what error you are having.
