System Identification Toolbox 7.4

System Identification Toolbox™ software lets you construct mathematical models of dynamic systems from measured input-output data. This data-driven approach helps you describe systems that are not easily modeled from first principles or specifications, such as chemical processes and engine dynamics. It also helps you simplify detailed first-principle models, such as finite-element models of structures and flight dynamics models, by fitting simpler models to their simulated responses.
