datastore and .mat files

I have a few .mat files containing a table of variables. I tried using datastore for the files so that then I can create timetables and apply timerange to select the rows of data within the specificed time. my scripts looks like this:

   warning off
   ds_loc = 'Z:\Desktop\*.mat';
   ds = datastore(ds_loc);
   ds.Delimiter = ' ';
   ds.MultipleDelimitersAsOne = 1;
   ds.SelectedFormats(1) = {'%{dd/MM/yyyy HH:mm:ss}D'}; 
   warning on

   tt = tall(ds); 
   ttab = table2timetable(tt) 
   strt_time = '03/12/2018 10:00:00'
   end_time = '03/13/2018 00:00:00'

   warning off 
   S1 = timerange(strt_time,end_time);
   warning on 
   S2 = ttab(S1,:)

this script works fine with .txt files but with .mat files I get the error:

   Error using datastore (line 114)
   Cannot determine the datastore type for the specified location.

   Specify the 'Type' name-value pair argument to indicate the type of datastore to create.

   Error in cls_test (line 10)
   ds = datastore(ds_loc);

Please could someone advise on what I'm doing wrong?

You can use fileDatastore for .mat files. An example of this can be found in the doc here .
