| contents | <p>A Regularized Hybrid-Optimization Framework for High-Resolution Modeling of the Lithospheric Stress Field: Application to the Makran–Zagros Collision Zone</p> <p>This repository implements a regularized hybrid-optimization framework for high-resolution lithospheric stress modeling. The approach uses a location-aware Inverse Total Variation (iTV) regularizer, Bayesian hyperparameter tuning, and a final constrained solve via SQP. The package provides MATLAB (R2016b baseline) and GMT (5.x baseline) pipelines, input datasets, and ready-to-use outputs for any region. The implementation extends and generalizes the classical frameworks of Flesch et al. (2001) and Hirschberg et al. (2019).</p> <p>Applicability. The optimization framework is generic and can be applied to any inverse/signal problem with a non-Gaussian posterior where piecewise-smooth structure and edge preservation are important.</p> <p>How to run<br>1) MATLAB:<br> - Configure input paths under `data/`<br> - Run: src/matlab/stress_calc.m<br> (calls moho2gpe.m, grav_stress.m, basis_fns.m, tot_stress.m)<br> - Final grids: results/grids/<br>2) GMT (5.x):<br> - From src/gmt/scripts/ run, e.g.:<br> bash src/gmt/scripts/tot_shmax_plot_gmt_v1.0.0.sh<br> - Figures are written to: figures/</p> <p>Requirements<br>- MATLAB R2016b+, Optimization Toolbox (fmincon/SQP; `bayesopt` if available)<br>- GMT 5.x (newer GMT may require minor edits)<br>- Windows/Linux/macOS</p> <p>Please cite (both)<br>- Preprint (SSRN): Dashtbazi, A., & Voosoghi, B.
