WebAs you can see, square matrices are usually named by their order, that is, a square matrix of order 2 means that it is a 2×2 dimension matrix (2 rows and 2 columns). Likewise, a square matrix of order 3 is a 3×3 dimension matrix (3 rows and 3 columns). Types of square matrices. Below are the most important types of square matrices that exist. WebThe square matrix K = ATCA ∈R × ... and 6 simply perform matrix multiplications with diagonal matrices, Line 5 is a sum of outer product. The computational complexity of the algorithm is mainly characterized by the computation of an orthogonal basis for the kernel of (C12 A)T (as the other operations are very simple).
