“Oh shit I better remember all that matrix algebra I forgot already!”

…Then takes a class on anything with 3d graphics… “oh shit matrix algebra again!”

…then takes a class on machine learning “urg more matrix math!”

EEs actually had a head start on ML, especially those who took signal processing.

I remember vectors in 3D graphics but I don’t recall them in EE 101. maybe I blotted it out.

From my experience, complex exponentials were a much more important fundamental than matrices.
