Your interpretation of “matrix theory” doesn’t seem to have much to do with the course mentioned by RandomInteger4. You can see what the content was by looking at the textbook mentioned, https://amzn.com/0521548233 https://amzn.com/0521548233 Judging from the reviews it seems like it is a good reference book of intermediate/advanced linear algebra topics which researchers in other fields found useful as a reference. I’m guessing this course was intended as maybe a 3rd course in linear algebra, with a slightly applied flavor. Giving it a different name makes it easier for students to distinguish the course than just calling it “Linear algebra 3A” or whatever.
