1""" 

2 

3Module to define exceptions to be used in sympy.polys.matrices modules and 

4classes. 

5 

6Ideally all exceptions raised in these modules would be defined and documented 

7here and not e.g. imported from matrices. Also ideally generic exceptions like 

8ValueError/TypeError would not be raised anywhere.
