(Row Replacement) Another very common row operation from lincar algebra is the row replacement. operation. With this operation, we begin with an original matrix and produce a new matrix where one row has been replaced by the result of adding a mutiple of another row to it. This can be denoted R, - R, + aR, where a represents the multiplier and R, and R; refer to rows i and j. rov_replace Function: Input parameters: • an m x n matrix A (note: the dimensions are not passxd in) • two scalars which represent the rows i and j described above, respectively • a sealar which represents the multiplier a described above Output parameters: • a new matrix representing the resulting matrix from performing the de- sired row replacement operation on A A possible sample case is: > mat_B = row_replace ([1:4 ; 2:5 ; 3:6 ; 4:7], 2, 3, -1) mat B = 1 2 3 4 -1 -1 -1 3 4 5 4 5 6 7 -1
