Using the →ExponentialChange
component from the SourcesOrSinks
package, this component allows to model exponential change at either a constant fractional rate
or at an exogneous rate given by the input u_rate
.
The process by default is active over the whole simulation run, but can be restricted to an on-off period using tc = TimingChoices.period
and the parameters startTime
and stopTime
. Any given rate—rate
or u_rate
—can be modified by multiplication with an optionally given input u.
