In this exercise, complete the following files: - 1 of 1 - interchange (A, i, j) 1.--.--cangular matrix A and two integers i and j. Output: the matrix resulting from swapping rows i and j, i.e. performing the row operation R; Rj. function B = scaling (A, i, s) Input: a rectangular matrix A, an integer i, and a scalar s. Output: the matrix resulting from multiplying all entries in row i by s, i.e. per- forming the row operation Ri+ sRi. function B = replacement (A, i, j, s) Input: a rectangular matrix A, two integers i and j, and a scalar s. Output: the matrix resulting from adding s times row j to row i, i.e. performing the row operation RiRi + sR; Implementation tips: In each of these functions, you should check that the input indices i and j are in range, i.e. 1 n. You can generate some simple matrices for testing on using the functions eye (m,n), ones(m,n), and randi(10,m,n).
