A time-frequency analysis specialized for mechanical engineering.
Related to the paper "Velocity Guided Chirplet Transform: Ultilizing Rotation Speed Information in Time-frequency Analysis" (DOI: 10.1109/TIM.2025.3650244).
VGCT.m is the main algorithm;
Example.m is the simulation example exhibited in the paper;
SignalGenerating.m and dFMAM.m construct the simulation signal of the example, in which an additional toolbox is required;
dataSim.mat is the data adopted in the paper;
renyi.m and integ2d.m compute the Renyi Entropy, which are not written by me.
