Hello,

I have written a wrapper class for HDF 5 datatypes. At this time I read a static array of my HDF structur into a Boost matrix with this code:

ublas::matrix<T> l_mat(l_size[1],l_size[0]);

T l_data[l_size[0]][l_size[1]];

l_dataset.read( l_data, p_datatype );

for(std::size_t i=0; i < l_mat.size1(); ++i)

for(std::size_t j=0; j < l_mat.size2(); ++j)

l_mat(i,j) = l_data[j][i];

T is a template variable like double or float, p_datatype is the datatype in the HDF file. l_dataset is the structur of the HDF file with the data. This code works but my question is, can I create the Boost matrix only from the static array l_data? I would like to remove the both for-loops to this

T l_data[l_size[0]][l_size[1]];

l_dataset.read( l_data, p_datatype );

ublas::matrix<T> l_mat(l_data);

or can I use a reference of the data structure of the matrix like:

ublas::matrix<T> l_mat(l_size[1],l_size[0]);

l_dataset.read( &l_data.getDataRefernce(), p_datatype );

Do you have any idea for filling the matrix?

Thanks

Phil
