Determine if data type is variable-length string
output = H5T.is_variable_str(type_id)
output = H5T.is_variable_str(type_id)
returns
a positive value if the data type specified by type_id
is
a variable-length string and zero if it is not. A negative value
indicates failure.
fid = H5F.open('example.h5'); dset_id = H5D.open(fid,'/g3/VLstring2D'); type_id = H5D.get_type(dset_id); if H5T.is_variable_str(type_id) > 0 fprintf('variable length string\n'); end
