There is a matrix equation,

, where,

and

. Elements of

are known. Also

are known. Therefore for each n I want to calculate the vector

as a function of

. As I understand I cannot use inverse operation as the unknown variable

is sitting there. Is there any way to handle this in MATLAB?

Or, the only option is to calculate

and write each element of

I wish to get a equation

. The thing is the left hand side is a function of

. Therefore I need to know how these are related to

to to be able write it in a form like that. Yeah I guess I have to try it symbolic calculation. Thanks for the suggestion.

I'd just determine D1 numerically and calculate "a" from the above relation.

Then I'd check (also numerically) whether Dn*zeta_n = a*(zeta_n-1 + zeta_n+1) is true for n > 1.

This is not a rigorous proof, but ok as a start, I guess.
