Structural dynamic identification  Enhanced Frequency Domain Decomposition 

TruDI (sTructural Dynamic Identification) is a Matlab toolbox for structural dynamic identification developed within the framework of the MONSTER Project (Structural Monitoring of Heritage Buildings by Wireless Technologies and Innovative Computing Tools, 2014-2016). TruDI implements the Enhanced Frequency Domain Decomposition (EFDD), a widely spread non-parametric technique for operational modal analysis developed by Batel. TruDI allows to calculate the natural frequencies, damping ratios, mode shapes and damped frequencies of a structure as well as the MPC (Modal Phase Collinearity) for each mode.
