Class MacroDiffRules

java.lang.Object

org.lsmp.djep.djep.diffRules.ChainRuleDiffRules

org.lsmp.djep.djep.diffRules.MacroDiffRules

All Implemented Interfaces:

DiffRulesI

public class MacroDiffRules
extends ChainRuleDiffRules

Rules are specfied by a set of strings or 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)");
