%写hdf5数据
O2Adetails1.Location ='/GroupName';
O2Adetails1.Name = 'SdsName';

%写属性
attr = '0~255';
attr_details.Name = 'units';
attr_details.AttachedTo = '/GroupName/SdsName';
attr_details.AttachType = 'dataset';

attr1 = '0~255';
attr_details1.Name = 'DESCRIPTION';
attr_details1.AttachedTo = '/GroupName/SdsName';
attr_details1.AttachType = 'dataset';

hdf5write('E:\result.h5', O2Adetails1, SdsData, attr_details, attr,attr_details1, attr1,'WriteMode', 'overwrite');

%第二种,包括"h5create","h5disp","h5info","h5read","h5readatt","h5write"和"h5writeatt"等函数
%h5create(filename,datasetname,size,Name,Value),h5create必须制定数据集的维数，不好用
h5create('myfile.h5','/DS1',[10 20]);
mydata = rand(10,20);
h5write('myfile.h5', '/DS1', mydata);

%---------------------------------------------------------------------------------------------------------------
%第三种,比较好用，类似于idl中的hdf5读写，主要包括：H5F.*、H5G.*、H5D.*、H5A*、H5T.*、H5S.*等相关函数
fid = H5F.create('myfile.h5');
type_id = H5T.copy('H5T_NATIVE_FLOAT');

%HSCO2_O2A_ARP分组
group_id=H5G.create(fid,'HSCO2_O2A_ARP','H5P_DEFAULT','H5P_DEFAULT','H5P_DEFAULT');
dims = [1016 8 6];
h5_dims = fliplr(dims);
h5_maxdims = h5_dims;
space_id = H5S.create_simple(3,h5_dims,h5_maxdims);
dset_id = H5D.create(group_id,'RadianceConversionO2A',type_id,space_id,'H5P_DEFAULT');
H5D.write(dset_id,'H5ML_DEFAULT','H5S_ALL','H5S_ALL','H5P_DEFAULT',RadianceConversionO2A);

H5S.close(space_id);
H5T.close(type_id);
H5D.close(dset_id);
H5G.close(group_id);
H5F.close(fid);
h5disp('myfile.h5');
