Create a block selector, a filter, and a rule for the selector. Add rules to the filter. Then, remove a rule from a filter.

Open the model. Specify coverage settings and turn on coverage recording.

modelName = 'slcoverage_lct_bus';
open_system(modelName);
set_param(modelName,'CovMetricStructuralLevel','MCDC','RecordCoverage','on');

Create two BlockSelector objects, bl and bl1.

bl = slcoverage.BlockSelector(slcoverage.BlockSelectorType.BlockType,'RelationalOperator');
id = Simulink.ID.getSID('slcoverage_lct_bus/slCounter/And');
bl1 = slcoverage.BlockSelector(slcoverage.BlockSelectorType.BlockInstance,id);

Create a filter object, create two rule objects, and add each rule to the filter object.

filt = slcoverage.Filter;
rule = slcoverage.FilterRule(bl,'Tested elsewhere',slcoverage.FilterMode.Exclude);
rule1 = slcoverage.FilterRule(bl1,'Value is never greater than 0');
filt.addRule(rule);
filt.addRule(rule1);

Review the rules. Look the first rule in the array.

fi = filt.rules
fi(1)
fi = 

  1×2 FilterRule array with properties:

    Selector
    Mode
    Rationale

ans = 

  FilterRule with properties:

     Selector: [1×1 slcoverage.BlockSelector]
         Mode: Exclude
    Rationale: 'Tested elsewhere'

Remove the first rule that you added. Then review the rules to see that the first rule that you added is removed.

filt.removeRule(rule);
fi = filt.rules
fi = 

  FilterRule with properties:

     Selector: [1×1 slcoverage.BlockSelector]
         Mode: Justify
    Rationale: 'Value is never greater than 0'
