I have dataset in h5 format and i read that data using
x = hdf5read(file.GroupHierarchy.Datasets(1));
now x contain 2x1024x31200, I want to extrace 2x1024x10000 from it.

If you want to extract first 10000 elements from the x, you can just do
extracted_x = x(:,:,1:10000);
% Or if you want specific indexing
begin = 101;
conclude = 10100;
extracted_x = x(:,:,begin:conclude);
Also, just for your information, MATLAB now recommends h5read instead of hdf5read (c.f. here).
Hope this helps.
