Size of data type in bytes


type_size = H5T.get_size(type_id)


type_size = H5T.get_size(type_id) returns the size of a data type in bytes. type_id is a data type identifier.


Determine the size of the data type for a specific dataset.

fid ='example.h5');
dset_id =,'/g3/bitfield2D');
type_id = H5D.get_type(dset_id);
type_size = H5T.get_size(type_id);
