Is there any code for calculation for Distribution of Relaxation Times (DRT) in Time domain for battery data?

Hello,
I wanted to calculate Distribution of Relaxation times (DRT) in Time domain as I have Pulse measurement data for a battery, is it possible to do so?

Out of the box, there is not a quick way to do this. However, there are tools such as the controls system toolbox, system identification toolbox, and RF toolboxes which give you the ability to go between frequency and time domain. We don't have existing exaples to do that. In most cases we usually extract a few time constants for a battery instead of a distribution which we do have better examples of: https://www.mathworks.com/matlabcentral/fileexchange/36019-battery-modeling?s_tid=srchtitle
