The signal output from Signal Editor does not match the expected signal created in the scenario. Why is this happening?

The time data imported from external experimental data or created as T2 = [0:0.02:10]' can cause discrepancies (diff) between the time steps used by Simulink, which may lead to unexpected simulation results.
In this case, replacing the time data with the Simulink time step as shown below can avoid the mismatch issue.
timeVector = timeStep * [startTime:numSteps-1]'
This is explained in the "Specifying Time Data" section of the following documentation page.

Additionally, the "Note" explains that time data obtained incrementally, such as [0:0.2:10], may not match Simulink's time steps, so please check that.
For more details, please refer to the following blog post.
