I have applied time-frequency transformation on simulation output. Now I'm interested to calculate different type of energy and entropy at different points. Can anyone help ?

Hi Ayushi,
The energy of signal at each frequency is the absolute value of the Fourier transform of the signal. The power at each frequency is the square of the energy.
For more information, have a look at this answer https://in.mathworks.com/matlabcentral/answers/302011-convert-the-time-domain-signal-into-frequency-domain-signal#answer_233885
Hope this helps.
