KotlingradExpression

class KotlingradExpression<T : Number, A : NumericAlgebra<T>>(algebra: A, mst: MST) : SpecialDifferentiableExpression<T, KotlingradExpression<T, A>>

Represents MST based DifferentiableExpression relying on Kotlin∇.

The principle of this API is converting the mst to an SFun, differentiating it with Kotlin∇, then converting SFun back to MST.

Parameters

T

The type of number.

A

The NumericAlgebra of T.

Constructors

KotlingradExpression

fun <A : NumericAlgebra<T>> KotlingradExpression(algebra: A, mst: MST)

Functions

derivativeOrNull

open override fun derivativeOrNull(symbols: List<Symbol>): KotlingradExpression<T, A>

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

Properties

The A instance.

val mst: MST

The MST node.
