  2. HDF Explorer • Version 1.4 just released • New features: support for HDF5 Dimension Scales

  3. Dimension Scales : HDF5 APIC code • Example: I have an array of 12 elements organized in a 3 X 4 matrix

  4. Dimension Scales : HDF5 APIC code • But the spatial phenomenon I am trying to model has different width and height definitions X Y

  5. Dimension Scales : HDF5 APIC code My array data of 12 elements: int dset_data[12] = {1,2,3,4,5,6,7,8,9,10,11,12}; My X axis spatial domain: int X[4] = {10,20,50,100}; My Y axis spatial domain: int Y[3] = {10,20,30};

  6. Dimension Scales : HDF5 APIC code Save my arrays as HDF5 datasets with the High Level HDF5 API function H5LTmake_dataset_int (fid,“My data",rank,dims, dset_data);

  7. Dimension Scales : HDF5 APIC codefor the X and Y arrays H5LTmake_dataset_int (fid,“X axis",rankx,dimsx, X); H5LTmake_dataset_int (fid,“Y axis",ranky,dimsy, Y);

  8. Dimension Scales : HDF5 APICall H5DSattach_scale function /* get the DS dataset id and dataset*/ did = H5Dopen(fid,” My data”); dsid = H5Dopen(fid,” X axis”); /* attach the “ X axis” dimension scale to “My data" at dimension 0 */ H5DSattach_scale(did,dsid,DIM0);

  9. Dimension Scales : HDF5 APICall H5DSattach_scale function /* get the DS dataset id and dataset*/ did = H5Dopen(fid,” My data”); dsid = H5Dopen(fid,” X axis”); /* attach the “ X axis” dimension scale to “My data" at dimension 0 */ H5DSattach_scale(did,dsid,DIM0);
