Rate

Rate of dose

The Rate property of a ScheduleDose object is a column vector instead of a row vector. For details, see Compatibility Considerations.

Description

Rate is a property of a RepeatDose or ScheduleDose object.

This property defines how fast a dose is given. If the rate is set to 0 or an empty array [], then it is interpreted as a bolus (instantaneous) dose.

For RepeatDose objects, you can parameterize the property by setting it to the name of a model-scoped parameter that is not being modified by a repeated assignment rule, an algebraic rule, or a rate rule. However, the parameter can be modified by an event.

Note

If you set the Rate property of a dose, you must also specify the Amount property of the dose, and set the DurationParameterName property to ''. This is because the duration is calculated from the amount and rate.

Tip

You can create a combination of bolus and infusion doses by setting the rate property of a ScheduleDose object to a vector containing zeros and non-zeros.
