    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.
