Package com.singularsys.extensions.djep.diffRules

Class MacroDiffRules

java.lang.Object

com.singularsys.extensions.djep.diffRules.ChainRuleDiffRules

com.singularsys.extensions.djep.diffRules.MacroDiffRules

All Implemented Interfaces:

DiffRulesI, JepComponent, java.io.Serializable

public class MacroDiffRules
extends ChainRuleDiffRules

Rules are specified by an expression string or a trees of nodes. The standard chain rule is applied

 diff(f(g(x),h(x)),x) -> df/dg dg/dx + df/dh dh/dx
 

for example

 DifferentiationVisitor dv = new DifferentiationVisitor(new TreeUtils(jep));
 DiffRulesI rule = new MacroDiffRules(dv, "sin", "cos(x)");
