What is a Type 2 matrix?

Type II. Definition. A v × v complex matrix W is a type-II matrix if. WW(−)T = vI. So if W is a type-II matrix then.

What does a 1 mean in Matrix?

Identity matrixThe inverse of a square matrix A, denoted by A-1, is the matrix so that the product of A and A-1 is the Identity matrix. The identity matrix that results will be the same size as the matrix A. Wow, there’s a lot of similarities there between real numbers and matrices.
