please use matlab and use the given work

The original csolve code is as follows

A hint to how this problem could run

Submit your m-file and a diary that shows how you tested the code. Modify csolve.m so that it outputs pivot and free. Then call upon this function in csolvefull.m. Submit the m-file for csolvefull.m, but not csolve.m Create a function csolvefull.m with input matrix A and a column vector b and no output. The function should display the rank, the pivot and free variables of A, the particular solution to Ax - b, and the special solutions for A. Test it using the system below 11 5 8 -4 0 2 15 -3 6-12 -8 -5 1 3 2 -5 6 9 Your display should be precisely the following: >> csolvefull(A,b) The rank of the coefficient matrix is 3 Pivot variables: 1 2 5 Free variables: 3 4 The particular solution is xp 0.4413 0.0829 0 0.3981 The special solutions are 0.5000 0.5000 1.0000 0.5000 1.5000 1.0000 0.0000 0.0000 Page 1 of 1 Submit your m-file and a diary that shows how you tested the code.
