Hello all -
I have scoured the internet and cannot find any example code for what
I am trying to do.
Using matlab, I am trying to insert a variable length integer array
(2 x 1) into a compound data type. I can insert a compound datatype
and I can insert variable length strings. Here is my code:
data.temp1 = uint32([7; 0]);
data.temp2 = int32([0; 0]);
intType1=H5T.copy('H5T_NATIVE_UINT');
sz(1) =H5T.get_size(intType1);
intType2=H5T.copy('H5T_STD_U32LE');
varType1 =H5T.vlen_create(intType1);
sz(2) =H5T.get_size(varType1);
sz(3) =H5T.get_size(intType2);
offset(1)=0;
offset(2:3)=cumsum(sz(1:2));
sz(3) = 0;
%
% Create the compound datatype for memory.
%
memtype = H5T.create ('H5T_COMPOUND', sum(sz));
varType1 =H5T.vlen_create(intType1);
varType2 =H5T.vlen_create(intType2);
H5T.insert (memtype,...
'resolution',offset(1),intType1);
H5T.insert (memtype,...
'badValues',offset(2), varType1);
filetype = H5T.create ('H5T_COMPOUND', sum(sz));
H5T.insert (filetype, 'Temp1', offset(1),intType2);
H5T.insert (filetype, 'Temp2, offset(2),varType2);
space = H5S.create_simple (1,fliplr(2), []);
%
% Create the dataset and write the compound data to it.
%
dset = H5D.create (BandStats, BandStatData{1}, memtype, space, 'H5P_DEFAULT');
H5D.write (dset, filetype, 'H5S_ALL', 'H5S_ALL', 'H5P_DEFAULT', data);
The code runs, but MatLab crashes after the write command.
Any help would GREATLY be appreciated.
Thank you.
Ben
