Method Detail

getIdentifiers

String[] getIdentifiers()

Delivers an array of Strings that describe the content of each dimension of the resulting array of this DESystem.

Returns:

An array of Strings which has the same length than the number given by FirstOrderDifferentialEquations.getDimension(). Each String describes the content of the given dimension.

containsEventsOrRules

boolean containsEventsOrRules()

This method is used to check if this differential equation system contains any events or rules that would require a special treatment by the numerical solver.

Returns:

flag that is true if any events or rules are contained in the differential equation system.

getPositiveValueCount

int getPositiveValueCount()

Returns:

the number of values in Y that have to be positive.

setDelaysIncluded

void setDelaysIncluded(boolean delaysIncluded)

Parameters:

delaysIncluded - Determines whether delay expression should be included in the calculation.
