This video explains the vocabulary used when solving matrices. Rows, Columns, Square Matrix, Row Matrix, Column Matrix, Zero Matrix, Equal Matrices

A **row matrix** is a matrix with only one row.

E is a row matrix of order 1 × 1

B is a row matrix of order 1 × 3

A **column matrix** is a matrix with only one column.

C is a column matrix of order 1 × 1

D is a column matrix of order 2 × 1

A column matrix of order 2 ×1 is also called a **vector** matrix.

A **zero matrix** or a **null matrix **is a matrix that has all its elements zero.

O is a zero matrix of order 2 × 3

A **square matrix** is a matrix with an equal number of rows and columns.

T is a square matrix of order 2 × 2

V is a square matrix of order 3 × 3

A **diagonal matrix** is a square matrix that has all its elements zero except for those in the diagonal from top left to bottom right; which is known as the **leading diagonal** of the matrix.

B is a diagonal matrix

A **unit matrix** is a diagonal matrix whose elements in the diagonal are all ones.

P is a unit matrix.
