The `fdd` algorithm module

This module provides implementation of the Frequency Domain Decomposition (FDD) algorithm [BZA01], the Enhanced Frequency Domain Decomposition (EFDD) algorithm [BVA01], and the Frequency Spatial Domain Decomposition (FSDD) algorithm [ZWT10], along with their adaptations for multi-setup experimental data [SARB21]. These algorithms are used in structural dynamics to identify modal parameters such as natural frequencies, damping ratios, and mode shapes from ambient vibration measurements.

Classes:

FDD: Implements the basic FDD algorithm for single setup modal analysis.
EFDD: Extends FDD to provide Enhanced FDD analysis.
FSDD: Implements the Frequency-Spatial Domain Decomposition, a variant of EFDD.
FDD_MS: Adapts FDD for multi-setup modal analysis.
EFDD_MS: Extends EFDD for multi-setup scenarios.

Important

Each class contains methods for executing the respective Frequency Domain Decomposition based algorithm, extracting modal parameters, plotting results, and additional utilities relevant to the specific FDD approach.

Note

Users should be familiar with the concepts of modal analysis and system identification to effectively use this module.
