Mode Decomposition using Independent Component Analysis

Mode shapes identification using independent component analysis

This example file shows mode shapes identifcation using independent component analysis (ICA) of 2DOF system subjected to impulse excitation. However it should be taken into account:

-The selected 2DOF system have orthogonal modes.
