Matrix Operator Method

Well, thanks, so it was useful, although my terminology is often a bit handwaved... :-). Good!

you can directly use the binomial series for computation?

No, but it looks very good. I'll give it a deeper look, thanks for the hint!

[update]
Well, in a second thought: in the form of

actually I used it extensely for the scalar and also for the vectorial case.
Applied to a vector of type V(x) = [1,x,x^2,...] it is
P * V(x) = V(x+1)
where P is the pascal-matrix containing the binomial-coefficients.
I dealt a lot with this, and analoguously I derived the fractional and complex powers of P for the general complex solution
P^s * V(x) = V(x + s)
via matrix-logarithm of P (which is an extremely basic object, btw! see this on a t-shirt :     and in wikipedia at "pascal-triangle" )
Then, with iterated application of P as an operator, just equivalently as described here related to tetration, one can find the interesting Faulhaber/Bernoulli-matrix and zeta/eta-values at negative exponents.
Summing of like powers which may be seen as a preliminary training :-)
