Please solve this problem in MATLAB. Thank you so much!!

I Elementary row operations 3 points) As this may be your first experience with serious programming in MATLAB, we will ease into it by first writing some simple functions that perform the elementary row operations on a matrix: interchange, scaling, and replacement. Specification: function B = interchange (A, 1, j) Input: a rectangular matrix A and two integers i and j. Output: the matrix resulting from swapping rows i and j, i.e. performing the row operation Ri 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. ction 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 row7 to row i, i.e. performing the row operation Ri Ri + sRj. Implementation tips: In each of these functions, you should check that the input indices i and j are in range, i.e. 1 5 i K m and 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)
