Rules - Array of rules in model object

Description

The Rules property shows the rules in a Model object. Read-only array of SimBiology.Rule objects.

A rule is a mathematical expression that modifies a species amount or a parameter value. A rule defines how certain species and parameters should interact with one another. For example, a rule could state that the total number of species A and species B must be some value.

You can add a rule to a model object with the addrule method and remove the rule with the delete method. For more information on rules, see addrule and RuleType.

Characteristics

Applies to	Object: model
Data type	Array of rule objects
Data values	Rule object
Access	Read-only

Examples

1. Create a model object, and then add a reaction object.

   modelObj = sbiomodel ('my_model');
   reactionObj = addreaction (modelObj, 'a + b -> c + d');

2. Add a rule.

   ruleobj = addrule(modelObj, '10-a+b')

   MATLAB returns:

   SimBiology Rule Array
   
   Index:    RuleType:    Rule:
    1        algebraic    10-a+b
