Query object for finding blocks that are potentially problematic for linearization
linqueryAdvise creates a custom query object for finding the
blocks in a linearization result that are potentially problematic for
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
with custom query objects. Alternatively, you can analyze linearization diagnostics using the
Linearization Advisor in the Model Linearizer. For more information on finding
specific blocks in linearization results, see Find Blocks in Linearization Results Matching Specific Criteria.

Load the Simulink model.

Linearize the model and obtain the
opts = linearizeOptions('StoreAdvisor',true); io = getlinio(mdl); [sys,op,info] = linearize(mdl,io,opts); advisor = info.Advisor;
Create query object, and find all the linearized blocks that have potentially problematic linearizations.
qAdvise = linqueryAdvise; advAdvise = find(advisor,qAdvise)
advAdvise = LinearizationAdvisor with properties: Model: 'scdpendulum' OperatingPoint: [1x1 opcond.OperatingPoint] BlockDiagnostics: [1x3 linearize.advisor.BlockDiagnostic] QueryType: 'Linearization Advice'
linqueryAdvise object is equivalent to creating the
following custom query:
qPath = linqueryIsOnPath; qZero = linqueryIsZero; qBlkRep = linqueryIsBlockSubstituted; qDiags = linqueryHasDiagnostics; q = qPath & (qZero | qDiags | qBlkRep); advisor_new = find(advisor,q);
You can also create custom queries for finding specific blocks in linearization results using the Linearization Advisor in the Model Linearizer. For more information, see Find Blocks in Linearization Results Matching Specific Criteria.
