I haven't played much with ublas, but it seems like you can easily construct a GIL view from ublas matrix: typedef boost::numeric::ublas::matrix<float> Matrix; Matrix m(3, 3); float* data=&m.data()[0]; // is there a better way? gray32f_view_t gv=interleaved_view(m.size1(), m.size2(), (gray32f_ptr_t)data, m.size1()*sizeof(Matrix::value_type)); fill_pixels(gv, bits32f(0)); Lubomir

vigra's inheritance structure is good for multi dimensional operation(tensor operation).

vigra::MultiArrayView -> vigra::MultiArray -> vigra::Matrix vigra::MultiArrayView -> vigra::BasicImageView

But I can't find similar relation among GIL, boost::numeric::ublas, boost::multi_array

My request is interface to ublas like this

view_mat = view(ublas::matrix) gray32f_image_t dist_img=resampling(view_mat)

Then GIL can use LAPCK via ublas. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
