Hi all,
I run this code to read dataset in my test.hdf5 file. It return me 0.6996 instead of the whole 0.699552191362574. Please guide.
hinfo = hdf5info('test.hdf5');
dset = hdf5read(hinfo.GroupHierarchy.Datasets(1));
and here is my test.hdf5 file. test.hdf5

Look at the documentation for format.
>> hinfo = hdf5info('test.hdf5');
dset = hdf5read(hinfo.GroupHierarchy.Datasets(1));
dset
dset =
0.6996
>> format long
>> dset
dset =
0.699552191362574
