Re: [ublas] Iterate over all elements of a matrix

I suppose you are talking of dense matrices (i.e.
boost::numeric::ublas::matrix).
If it is so, you can use the "data()" method, that returns a reference to
the internal array that holds
matrix elements. This array has a begin() and an end() method, through which
you can iterate through
elements.

Sparse matrices have a different internal structure, but also in this case,
you can find the internal
array that holds non-zero values (look at the header files, particularly to
the public methods).
