What is the simplest way to do this. I have a matrix M (square and over ZZ, but that is not so important). I want to make another matric of the same size & base. I have not explicitly constructed the associated matrix space, but I know that I can get it wth M.parent(), so doing newM = M.parent()(0) would work, but is there something more natural?
Do you want to *copy* a matrix or construct a new matrix with the same parent? In the former case, just use copy(). In the latter case, what you did seems right. The fact that you have not *explicitly* constructed the matrix space doesn't matter, it exists anyway.
Of course, in Cython, there are much more efficient ways. -- You received this message because you are subscribed to the Google Groups "sage-support" group.
