/Sci/, what the hell is this notation?

The first week of my Vibrations/Optics class, we get a basic math review. And most of it is literally middle-school tier.

Somehow I've gotten stuck on this. I've seen and used matrices before, but only in the case of augmented matrices for systems of linear equations, and I've never seen this kind of notation before.

What is this? I don't even need the answer, just the term to Google.

Thanks /sci/entists.

Determinant of a matrix?
Remember learning about Eigen Values?
Or about determinants?

Take the determinant of those matrices and set them equal to the value given.

Thanks. No idea how I didn't find that googling.

what kind of middle school did you go to where they taught determinants of complex matrices?
