Specify species and parameter interactions
The Rule property contains a rule that 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. Rule is a MATLAB® expression that defines the change in the species object quantity or a parameter object Value when the rule is evaluated.
Note: If you set the Rule property for an algebraic rule, rate rule, or repeated assignment rule, and the rule expression is not continuous and differentiable, see Using Events to Address Discontinuities in Rule and Reaction Rate Expressions before simulating your model.
|Applies to||Object: rule|
|Data type||char string|
|Data values||char string defined as species or parameter objects. Default is empty.|
Create a model object, and then add a reaction object.
modelObj = sbiomodel ('my_model'); reactionObj = addreaction (modelObj, 'a + b -> c + d');
Add a rule.
ruleObj = addrule(modelObj, '10-a+b')
