Hello, I am new to stan.

I was able to install stanc3, cmdstan, rstan, cmdstanr and to run a simple regression in Getting Started.

How can I run the `transformed parameters`

block of stan code?

I would like, for example, to run an example solving an algebraic equation.

This example is deterministic and there is no point to use `sample`

method in cmdstan(r).

I was able find a way to call `algebraic_solver`

written directly in C++.
