Entries

The numbers that appear in the matrix

Term for a Matrix when the dimensions are the same, as well as the corresponding entries.

Row Matrix or Row Vector

A matrix with a single row

Column Matrix or Column Vector

Matrix with a single column

Square Matrix

Associative Law

A + (B + C) = (A + B) + C

A + B = B + A

Commutative Law

A + O = O + A = A

Additive identity law

A + (−A) = O = (−A) + A

Additive inverse law

c(A + B) = cA + cB

Distributive law

(c + d)A = cA + dA

Distributive law

1A = A

Scalar unit

0A = O

Scalar zero

Transposition

A^T
