Interface ICMLFunctionExpression

All Superinterfaces:

com.hazelcast.nio.serialization.DataSerializable, ICMLBlock, ICMLFunctionBase

All Known Implementing Classes:

CMLFunctionExpressionAdapter, GainExpFunction, GateValueExpFunction, HighValueExpFunction, LowValueExpFunction

public interface ICMLFunctionExpression
extends ICMLFunctionBase

We have two basic concepts: Block (StaticBlock and ControlBlock) and Function Block is two-way, which means you can find y from u and u(0) from y(0) Function is only way. You can only find y from a set of u(s). So function cannot put in the main path between RefPoint and Controller output This interface is design to represent function with a set of inputs, describing by expressions

Method Summary

Modifier and Type	Method and Description
boolean	addInputExp(ExpCalculator exp) add a input expression, describing an input expression
double	eval(double[][] dAry) evaluate function value based on the input double arrays, each array is for input expression calculation
java.util.List<ExpCalculator>	getInputExpList() get the input expression list
