Computational Data and MATLAB Codes for Fuzzy Parametric Uncertainty Propagation in a Fractional Reaction–Diffusion Hahnfeldt Tumor–Vascular Model

Abstract

This repository contains the MATLAB codes and numerical data supporting the computational results of the study “Fuzzy Parametric Uncertainty Propagation in a Fractional Reaction–Diffusion Hahnfeldt Tumor–Vascular Model.” The computational framework combines Caputo fractional temporal dynamics, spatial diffusion, and triangular fuzzy representations of uncertain biological and diffusion parameters. The archived materials include nominal fractional-order simulations, parameter-wise fuzzy uncertainty propagation, grouped biological and spatial uncertainty analyses, and numerical results describing the dependence of propagated uncertainty on fractional order. The included CSV files contain the principal numerical results reported in the study, while the MATLAB scripts enable reproduction of the corresponding computational analyses. No experimental, clinical, or personally identifiable data are included; all archived data were generated computationally from the mathematical model.
