SUMMARY
The discussion centers on the multiplication of matrix M with matrix A or vector c, specifically addressing the conditions under which these operations are valid. It is confirmed that matrix A (3x3) and vector c (3x1) can be multiplied, but division is not applicable in this context. The conversation highlights the necessity of using the inverse of matrix A (denoted as A-1) for multiplication, provided that A is non-singular. Additionally, the importance of determinants in determining the invertibility of matrix A is emphasized.
