Description

Summary

Application or interface to calculate some or all of the eigenvalues of a model (SMIB) or system model’s Jacobian at a given operating point.

Rationale

Used frequently in literature and practice

Description

Return eigenvalues or subset of eigenvalues using sparse methods so its scalable

Additional information

Unsure if SUNDIALS has built in API for this

Research direction

No file, test, or entry point is named. Start by locating the existing SMIB or system-model Jacobian interfaces and checking whether SUNDIALS support is already used. Done means defining an interface that returns all or selected eigenvalues at an operating point with sparse methods that scale.
