Before you can linearize a system, make sure a Signal Consumer block (for example, a plot block or export block) is directly or indirectly connected to the system to be linearized.
If you have not simulated the diagram containing the system to be linearized, Embed automatically simulates for one time step before linearization. To simulate to a specific operating point, use Go, Stop, and Continue in the System menu, or the corresponding , , and buttons in the toolbar.
