Proportionality expresses the fact that the rate of change for an influenced stock B is proportional to the net rate of change for an influencing stock A, which is connected via the stockInfoInput. The factor of proportionality k is given by the parameter coefficient. The rate of change for the stock B that is connected to the flowPort accordingly is given by the following equation, which uses Newton's dot notation for rates:

Notes

• The given coefficient can optionally be multiplied by an exogenous input u.


• By setting coefficient = 1 the input u can be used to provide a variable factor of proportionality.
