initial value problem-difference method

[-MFra-]

Hello everyone. I have a problem with a difference method, shown here below. (The results are different from those of the text). Some of you could kindly say me  if I'm wrong or the text is wrong? thanks a lot.

Yours sincerely F. M.

May be my example 18.10-18-12 here Study 18. Differential Equations in Thermal Engineering help you!

Thanks Valery,

the answer is very interesting and very instructive for the use of pdesolve. Thanks again.

However, it does not answer my question, namely: whether  the difference method and the  amplification matrix are correct.

With best regards.

I apologize, the differential equation considered, it is with constant coefficients.
