Yes. > What I want to do actually is to use the method > sage.matrix.matrix.is_Matrix(). > > This is perhaps a novice's question... Thank you in advance. It's not a novice question. Try putting " import sage.matrix.matrix" as the line *right* before you use "sage.matrix.matrix.is_Matrix()". I.e., do the import in the function, not at the module level.
