Column Matrices : A matrix is said to be a column matrix if it has only one column . In general , A = [ aij ] m × 1 is a column matrix of order m × 1 .
Row Matrices : A matrix is said to be a column matrix if it has only one Row . In general , A = [ aij ] 1 × n is a column matrix of order 1 x n .
Square Matrices : A matrix , in which the number of rows is equal to the number of columns , is said to be a square matrix . Thus an m × n matrix is said to be a square matrix if m = n and is known as a square matrix of order ‘ n ’. In general , A = [ aij ] m × m is a square matrix of order m .
