2 6 8
[9 4 7]
3 1 0
Rows:
In matrix horizontally represented entries are called rows
In above matrix (2 6 8), (9 4 7), (3 1 0) are rows of matrix.
Columns:
In a matrix entries which are represented in a vertical way are called
columns.
2 6 8
In above matrix (9) , (4) , (7) are columns of matrix.
3 1 0
Order of a matrix:
If a matrix has m number of rows and n number of columns, then
order of matrix will be m- by- n
