Types Of Matrices
A matrix may be classified by types. It is possible for a matrix to belong to more than one type. 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.
