This is the pre-2018 NNT API still used in the official "Getting Started with Neural Networks Using MATLAB" tutorial; the dlnetwork / trainnet lane (T1–T3) is the project's answer for current-era nets ...

Building on these results, we develop a reduced‐order analytical model using logistic regression to relate train speed (5.0–9.0 m/s) to peak force, maximum displacement, and energy absorption, ...
