Rules specifying how to differentiate functions.

Class Summary

Class	Description
ChainRuleDiffRules	Abstract base class for function which are differentiated using the chain rule.
DivideDiffRule	Differentiates a division with respect to a variable.
IfDiffRule	Differentiates functions like if(cond,trueExpr,falseExpr) where the first argument should not be differentiated, but subsequent ones should be.
MacroDiffRules	Rules are specified by an expression string or a trees of nodes.
MacroFunctionDiffRules	For functions defined by expressions this rule automatically calculates the derivative.
MultiplyDiffRule	Differentiates a product with respect to a variable. diff(y*z,x) -> diff(y,x)*z+y*diff(z,x)
PassThroughDiffRule	Rules like Sum where diff(sum(a,b,c),x) -> sum(da/dx,db/dx,dc/dx) are instance of this class.
PowerDiffRule	Differentiates a power y^z with respect to a variable.
ZeroDiffRule	Rules like diff(x > y,x) -> 0 where the derivative should be zero.
