Dear all,

My name is Joaquim Duran. I'm new to this mail list.

I'm using ublas for signal processing and I'm interested that the
matrix have a similar interface to a vector, using a proxy, to apply
algorithms designed for vectors. To get an idea, if the element of a
vector is a double, then the element of a row facade is a column. If
this possible to get this behavior using existing proxies?

I'll detail which is the expected behavior of the proxy:

Matrix      Column Proxy
--------       --------------------
begin2()    begin()
end2()       end()
rbegin2()   rbegin()
rend2()      rend()
size2()      size()
resize2()   resize()
*iter: double  matrix_row(matrix, i)

Matrix      Row Proxy
--------       --------------------
begin1()    begin()
end1()       end()
rbegin1()   rbegin()
rend1()      rend()
size1()      size()
resize1()   resize()
*iter: double  matrix_column(matrix, i)

Example: Sort the columns of a matrix based on their module:

using namespace boost::numeric::ublas;

template <typedef Vector>
bool less_module(const Vector& v1, const Vector& v2)
{
     return
}

main()
{
     vector v1;

}
