Hi, I'm completely new to matlab and I have a dataset of time and temperature. I want to apply the Ziegler–Nichols method to this data. For this, I want to pass a tangent line passing through the inflection point, how can I do it? Thank you in advance for all your answers. Attached are data as excel file and txt file.
