SpecialDifferentiableExpression

interface SpecialDifferentiableExpression<T, out R : Expression<T>> : DifferentiableExpression<T>

A special type of DifferentiableExpression which returns typed expressions as derivatives.

Parameters

R

the type of expression this expression can be differentiated to.

Functions

derivativeOrNull

abstract override fun derivativeOrNull(symbols: List<Symbol>): R?

Differentiates this expression by ordered collection of symbols.

abstract operator fun invoke(arguments: Map<Symbol, T>): T

Calls this expression from arguments.
