How To build a *.mat to Use The "From File" Block On Simulink?

I want to build an input *.mat with the Simulink Block 'From File',

Code like follows:

daten_sim = timeseries(daten, time);
save('daten_sim.mat','daten_sim');

Now I use the Simulink Block 'From File' to run the daten_sim.mat.

But I always get the same error:

Simulink does not support loading the input data in file 'daten_sim.mat'. For data saved using MAT file versions prior to 7.3, Simulink can only load two-dimensional arrays consisting of one-dimensional, double, noncomplex samples. To load data of any other type, complexity or dimension, use a timeseries object and save the file using MAT file version 7.3 or later. For example, use: 'save file_name -v7.3 timeseries_object'.

Actually my MATLAB is already the version 7.3. I have no idea where I am wrong.

In Matlab versions from 7.3 onward, the default is still to use the -v7 MAT file version; you have to specifically use -v7.3 in order to get the extended file format.

Hi Where exactly do I change the settings? I seem to have the same problem while loading a .mat file in to a from file block. where is the path file->preferences-> general-> mat files found? As in where is the file? is it in matlab or the system files? Sorry if the question sounds a little dumb.

Thanks in advance

Thanks you very much, after setup in the

File->Preferences->General->Mat Files

i changed the orginal set to v7.3

now it works very fine!
