Why do I get a different response when using the "step" command in the command line and the scope in Simulink?

I have a MIMO (10 outputs and 5 inputs) state transition matrix I don't understand why do I get different responses when invoking a step input in the command line and in Simulink. Can someone give me a light on this?

It is because of the solver. In Simulink, you probably use variable step solver, which is more accurate. In MATLAB Command line, you can overcome this situation by making the simulation with a small step size that you define, so you will get more accurate results.
t = 0:1e-6:10;
step('your model',t)
Try the code above.

It is up to you. The code above is to improve the performance of the step function in command line.
