![(Row Replacement) Another very common row operation from linear 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and produce a new matrix where one row has been replaced by the result of adding a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.
row_replace Function:
Input parameters:
• an m xn matrix A (note: the dimensions are not passed in)
• two scalars which represent the rows i and j described above, respectively
• a scalar 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 =
