how to make an empty time vector

I want to design an vector and download in DSP. But When I set "cycling repetition" on the "from workspace pane".An error is" Cannot specify cyclic repetition in 'SPWM/From Workspace' when the time vector is explicitly specified for the data. The cyclic option is supported only when the data is in the form of a structure with an empty time vector."So I want to read the data repeatedly ,how can I do! Thanks!

You should make a structure which has fields 'time' and 'signals'.

'time' field must be empty (see below), 'signals' field must be structure with your data.

values = struct('values', YourData);

A = struct('time', [], 'signals',values);

then use A in "From Workspace" block with setting Sample time
