Large Simulink® models and blocks with complex initialization functions can slow linearization.
In most cases, the time it takes to linearize a model is directly related to the time it takes to update the block diagram (Simulink).
Use the MATLAB® Profiler to identify complex bottlenecks in block initialization functions.
In the MATLAB Profiler, run the command:
You can speed up the linearization of large models by disabling the Linearization Diagnostics Viewer in the Linear Analysis Tool.
The Linearization Diagnostic Viewer stores and tracks linearization values of individual blocks, which can impact linearization performance.
In the Linear Analysis Tool, in the Linear Analysis tab, uncheck Diagnostic Viewer.
Tip: Alternatively, you can disable the Linearization Diagnostic Viewer globally in the Simulink Control Design™ tab of the MATLAB preferences dialog box. Clear the Launch diagnostic viewer for exact linearizations in the linear analysis tool check box. This global preference persists from session to session until you change this preference.
When batch linearizing a large model that contains only a few
varying parameters, you can use
reduce the computational load.
