Read a timeseries with h5py

Hello Community,

I have matfile that I would like to read with h5py but I cannot understand the output. So I used HDF viewer to see if that could lead somewhere but I cannot understand how time series are stored in HDF5.

My example is simple, it is a matfile with just 1 timeserie :

timeseriechannel : 1*1 single simeseries

When I open it in the HDF5 viewer I get the following :

• timeserie = [3707764736 1 1 1 5] --> not the time and data I expected
• I find the time under /#refs#/p
• I find the data under /#refs#/y

How could I expect that ? I gues that some how there is a game of handle and reference, but I cannot find the standard anywhere.

Thank you in advance for the support.

Hello,

So I was also discussing with MATLAB support and it seems that they do not recommand to use HDF5 library to read their MAT file outside of MATLAB but rather their C Api. I think that's the key to my problem.

Regarding your proposal, that works but only in matlab, and I am trying to read that in a 3rd party application.

But again thank you again for the support and time spent with me :)

I do not have the HDF5, only the matlfile. Should I generate it from matlab?

And the end goal is to read directly the mat file in another software (uniplot). I cannot ask users to do the conversion step. I might be missing your point here.

Thanks
