Type of Matrix Details
Row Matrix A = [aij]1×n
Column Matrix A = [aij]m×1
Zero or Null Matrix A = [aij]mxn where, aij = 0
Singleton Matrix A = [aij]mxn where, m = n =1
Horizontal Matrix [aij]mxn where, n > m
Vertical Matrix [aij]mxn where, m > n
Square Matrix [aij]mxn where, m = n
Diagonal Matrix A = [aij] when i ≠ j
Scalar Matrix A = [aij]mxn where, aij = \left \{\begin{matrix} 0, & i\ne j \\ k, & i=j \\ \end{matrix}\right \}{
0,
k,
i
=j
i=j
} where k is a constant.
Identity (Unit) Matrix A = [aij]m×n where, {{a}_{ij}}=\left\{ \begin{matrix} 1, & i=j \\ 0, & i\ne j \\ \end{matrix} \right.a

1,
0,
i=j

Equal Matrix A = [aij]mxn and B = [bij]rxs where, aij = bij, m = r, and n = s
Triangular Matrices Can be either upper triangular (aij = 0, when i > j) or lower triangular (aij = 0 when i < j)
Singular Matrix |A| = 0
Non-Singular Matrix |A| ≠ 0
Symmetric Matrices A = [aij] where, aij = aji
Skew-Symmetric Matrices A = [aij] where, aij = aji
Hermitian Matrix A = Aθ
Skew – Hermitian Matrix Aθ = -A
Orthogonal Matrix A AT = In = AT A
Idempotent Matrix A2 = A
Involuntary Matrix A2 = I, A-1 = A
Nilpotent Matrix ∃ p ∈ N such that AP = 0
