Code and data for one-dimensional optimisation of indefinite- weight principal eigenvalues with asymmetric Robin parameters and a Schrödinger-type perturbation, revised adaptive-shooting archive

This archive contains the Python code and machine-readable numerical outputs supporting the manuscript “One-dimensional optimisation of indefinite-weight principaleigenvalues under inhomogeneous Robin conditions and a Schrödinger-type perturbation”. It includes the original one-dimensional transfer-matrix shooting code and its verification summary for the unperturbed problem, and the code, CSV outputs, and generated figures for the constant-potential Schrödinger extension, including the numerical verification of Corollary 3.6. A README file describes the folder structure, software requirements, and reproduction steps.
