How can I use FROM WORKSPACE CYCLIC REPETITION in Simulink?

Hello, I have a question. I want to use as input a signal repeating "n " times.
I have defined the input as follows:
entrada.time = [ 0 1 2 3 4 5 6 ] entrada.signals.values = [ 0 5 3 8 6 2 0 ]
I Know how to use the block "repeting sequence" , but I've seen that in the block From Workspace there is an option that is "Cyclic repetition", but me a message that says " The cyclic option is supported only When the data is in the form appears with a structure of an empty vector time . "
What I have to change my input signal?
Thank you very much

When you choose cyclic option, set your variable in the bloc "from worskspace" like below:
y.time=[ ]
y.signals.values=[ 0 5 3 8 6 2 0 ]'
y.signals.dimensions=1
Uncheck the option: "Interpolate data"
Don't forget to set the sample time, in your case it's 1

But in the case that the step is not constant, for example, the time table is:
y.time = [0 1 4 4.5 5 9 10] ' y.signals.values = [0 4 6 5 4 2.3 5] '
How should I define the variable in the workspace and options should be changed in the FROM WORKSPACE block?
Thanks

In this case, try another solution, the repeating sequence for example.

Save your input data to workspace first and save it as a structure without time option.
