Hi, I am programming and adaptor of the HDF5 library to handle, to some extend, multi_arrays in an elegant way. It turns out that when I try to save a multi_array_view, with strides and offsets, etc. HD5F still needs to know the logical size (shape) of the parent array (the one that has contiguous elements in memory). The paradox is that in order to save an array view I need to know the original array. The question is, is there an (elegant) way to reconstruct the shape of the original array just from the multi_array_view. For moments it seems imposible because array_view doesn't know even the dimensionality of the "parent" array (or it does?). The task is further complicated because many members that may have this information are actually private or protected within multi_array_view. This is an example of what I want: multi_array<2> A(extents[10][10]); multi_array_view<1> Aview = A[3][indeces[range(0,10,2)]]; desired_function(Aview); --> returns 10, 10. Thanks, Alfredo
