Is there any difference in calculation of Energy spectral density and Power spectral density using MATLAB?

Power Spectral Density
PSD=PSD= real(Signal).^2 + imag(Signal).^2;
Where Signal =FFT output
How can I find Energy Spectral Density?

Wouldn't it just be the sqrt(psd)?
By the way, there is a function in the Signal Processing Toolbox to get the PSD:
PSD = pwelch(timeDomainSignal);
