Description

I recently added jacobimatrix(P,n) to ClassicalOrthogonalPolynomials.jl as it was sort of needed for n x n truncations that preserved the Tridiagonal structure. But perhaps this interface makes sense for other operators like weaklaplacian and grammatrix?

Research direction

Start by reviewing the existing jacobimatrix(P,n) interface described in the issue and how it supports n x n truncations. Compare the desired weaklaplacian(P,n) and grammatrix(P,n) behavior for Int and Block values of n, then identify the project’s relevant tests or operator entry points. Done means the interface and expected truncation behavior are specified and covered for both n forms.
