Using Matlab:

Hint:

Submit your m-file and a diary that shows how you tested the code. Create a function csolve.m with input a matrix A and no output. The function should display the rank and the pivot and free variables of A. Test it using the matrix below. 5554 6 10 23-5 9 12 69-8 21 3 -57 Your display should be precisely the following: >> csolve(A) The rank of the coefficient matrix is 4 Pivot variables: 1 2 4 5 Free variables: 3 Tip: Use the for structure to display pivot and free variables
