Matrix equation solving error

When solving the AX=B (A matrix and B matrix files are in the attachment below), the solution is inconsistent with MATLAB's.

"inconsistent" means the two solutions are not identical?
Have you checked the error : ||X_matlab - X_superlu|| / ||X_matlab|| ?

It is obviously that X_superlu is different from X_matlab, comparing each element in Matrix X.
