Do we need Mat, Vec, TMmat, Diag, Sym and other matrix types?

I think for mathematics it is more important for easy handling,
to be able to get the element of a matrix a_ij by a(i,j) and not 
only by a[i-1,j-1].

The underlying storage concept is less important and depends just 
on the used libs, which should be the best (fastest) available 
for the purpose.
