Query object for finding blocks linearized using numerical perturbation
linqueryIsNumericallyPerturbed creates a custom query object
for finding all the blocks in a linearization result that are linearized using numerical
When you linearize a Simulink® model, you can create a
LinearizationAdvisor object that contains diagnostic information about individual block linearizations. To find block linearizations that satisfy specific criteria, you can use the
find function with custom query objects. Alternatively, you can analyze linearization diagnostics using the Linearization Advisor in the Linear Analysis Tool. For more information on finding specific blocks in linearization results, see Find Blocks in Linearization Results Matching Specific Criteria.

Linearize the model and obtain the

You can also create custom queries for finding specific blocks in linearization results using the Linearization Advisor in the Linear Analysis Tool. For more information, see Find Blocks in Linearization Results Matching Specific Criteria.
