H5A.read

Read attribute

Syntax

attr = H5A.read(attr_id)
attr = H5A.read(attr_id, mem_type_id)

Description

attr = H5A.read(attr_id) reads the attribute specified by attr_id. MATLAB® will determine the appropriate memory datatype.

attr = H5A.read(attr_id, mem_type_id) reads the attribute specified by attr_id. mem_type_id specifies the attribute's memory datatype and should usually be given as 'H5ML_DEFAULT', which specifies that MATLAB will determine the appropriate memory datatype.

    Note:   The HDF5 library uses C-style ordering for multidimensional arrays, while MATLAB uses FORTRAN-style ordering. If the HDF5 library reports the attribute size as 3-by-4-by-5, then the corresponding MATLAB array size is 5-by-4-by-3. Please consult "Using the MATLAB Low-Level HDF5 Functions" in the MATLAB documentation for more information.

Examples

fid = H5F.open('example.h5');
gid = H5G.open(fid,'/');
attr_id = H5A.open(gid,'attr1');
data = H5A.read(attr_id);
H5A.close(attr_id);
H5G.close(gid);
H5F.close(fid);
