Given that you know the different values in advance why not just define
>> t = sort([0 10:10:90 10:10:90 100]); >> values = [0 1 2 3 4 5 6 7 8 9]; % replace with your required values >> u = [values; values]; >> tu = [t(:) u(:)];
Then use tu as the variable in a From Workspace block?
To see what this will look like you can plot it in MATLAB >> plot(tu(:,1),tu(:,2));
(Yes you could use set_param (most likely in a MATLAB function block placed in a triggered subsystem with the trigger being a square wave set at the appropriate frequency but there doesn't seem to be any need to.)
