Identity or Unit Matrix If in the scaler matrix the value of k=1, the matrix is called the identity or unit matrix. It is denoted by I or U.
Involtary Matrix A square matrix A such that A2=I or (A+I)(A-I)=0, A is called involtary matrix.
The null matrix is also called the zero matrix. It is a matrix with 0 in all its entries.
can anyone give me an exact definition of payroll matrix................
yes is scaler
Zero Matrix When all elements of a matrix are zero than the matrix is called zero matrix. Example: A=|0 0 0|
Lower-triangular Matrix A square matrix A whose elements aij=0 for i
Diagonal Matrix A square matrix A which is both uper-triangular and lower triangular is called a diagonal matrix. Diagonal matrix is denoted by D.
A square matrix A is idempotent if A^2 = A. It's really simple
from data structure
Uper-triangular Matrix A square matrix A whose elements aij=0 for i>j is called upper triangular matrix.
Scaler. The electric field is its vector counterpart.
