Dear Matlab community,
I'm having problems when trying to calculate and plot the phase angle of a cylinder undergoing Vortex-Induced Vibrations.
I need to plot the following (just the solid black line):
(From: A Single Van Der Pol Wake Oscillator Model For Coupled Cross-Flow And In-Line Vortex-Induced Vibrations (Qu and Metrikine, 2020)).
I know this is a very specific question, but I already tried inumerous phase angle's functions that I found in the Matlab community, but nothing seems to work for me.
If anyone have the answer and/or a suggestion, I would be really grateful.
