To Workspace Block - Output Array Size Problem

I am working on a script that runs a simulink model that gets inputs from the script and forwards the output to the workspace. However, even though the input is a constant value, the output results in a 51*1 size array. Is there any chance to change the size of the output as a 1*1 array (like a constant value)?
Best regards

A Simulink simulation runs for a period of time. The output being 51x1 size array probably means the simulation ran for 50 steps. You could change the time to make it run just one step but that would not be a typical Simulink simulation. Maybe you just need to make it a MATLAB function dealing with input and output.


I created the simulink model since it is harder to code it on MATLAB. I am aware of that it is not the most efficient way to use a simulink model, not even close but since I am not that familiar with simulink, I am trying to run the model iteratively from workspace.
So, how can I change the number of steps, then?
Set the Solver, Step time, Stop time
Or just click "Step Forward" once/twice and then Stop.
