I'm new to Mathematica and would like to know if I can specify a
matrix where the number of rows / columns is not fixed.
As a simple example, how can I input a diagonal matrix with elements
(s1, s2, ..., sL) where I don't specify what L is?
I'd like to multiply together a few such matrixes and find the inverse
of the product, and would ideally like Mathematica to give me the
answer in terms of summations from 1 to L.
Hope this sounds possible...!
