The other algebra forum stated that it was NOT the place for questions about Matrices that were larger than 2x2, however, this question does not really seem to belong here either, so let me apologize in advance.
That being said, my textbook, after explaining determinate, minors, and coefficients for 3x3 matrices, just drops the topic. I bet that is not the end of the story though. I'm a little curious about non-square matrices, or matrices larger than 3x3.
Does anyone know of any sources or links that I could continue along this vein?
