Create copy of data space
output = H5S.copy(space_id)
output = H5S.copy(space_id) creates a new
data space, which is an exact copy of the dataspace identified by space_id.
The output argument is a data space identifier.
fid = H5F.open('example.h5'); dset_id = H5D.open(fid,'/g2/dset2.1'); space1_id = H5D.get_space(dset_id); space2_id = H5S.copy(space1_id); [~,dims1] = H5S.get_simple_extent_dims(space1_id) [~,dims2] = H5S.get_simple_extent_dims(space2_id)
