Do you do data science work with complex numbers?

I trained and initially worked in engineering simulation where complex numbers were a fairly commonly used concept. I haven’t seen a complex number since working in data science (working mostly with geospatial and environmental data).

Any data science buddies out there working with complex numbers in their data? Interested to know what projects you all are doing!
