with_tulpa_integrator: Run an expression under a chosen symplectic integrator

In tulpa: Templated Unified Library for Posterior Approximation in Bayesian Hierarchical Models

Run an expression under a chosen symplectic integrator

Description

Evaluate expr with the integrator set to name, then restore whatever was selected before – on an error as well as on success. The integrator selection is process-global, so a bare tulpa_integrator() call leaves every later fit in the session on the new scheme, and an error between setting and restoring leaves it there permanently.

Usage

with_tulpa_integrator(name, expr, mts_substeps = 4L)

Arguments

name	Integrator name, as for tulpa_integrator().
expr	Expression to evaluate. Evaluated in the caller's environment.
mts_substeps	Inner prior-force substeps for "mts" (default 4).

Value

The value of expr.

Examples

tulpa_integrator()   # unchanged
