Matrix Elementary Row Operation
The matrix in algebra has three row operations are called Matrix Elementary Row Operation. They are Swapping any two rows Multiply a row by constant Adding any two rows The row operation is carried out on a matrix to turn it a lower triangular matrix or a upper triangular matrix to find out solution vector for system of linear equations. Swap two rows The matrix A has 3 rows and 3 columns. Row R 1 and R 2 swapped - Both rows interchanged their elements. i.e R 1 becomes R 2 and vice versa. Add two rows The matrix A has 3 rows and 3 columns. Add two rows R 1 and R 2 - R 1 's each elements is added to R 2 's corresponding elements. resultant row replace row R 2 i.e R 2 -> R 1 + R 2 . Multiply a row by constant...
