Functions

abstract fun add(left: StructureND<T>, right: StructureND<T>): StructureND<T>

Addition of two elements.

binaryOperation

open fun binaryOperation(operation: String, left: StructureND<T>, right: StructureND<T>): StructureND<T>

Dynamically invokes a binary operation with the certain name.

binaryOperationFunction

open override fun binaryOperationFunction(operation: String): (left: StructureND<T>, right: StructureND<T>) -> StructureND<T>

Dynamically dispatches a binary operation with the certain name.

open fun bindSymbol(value: String): StructureND<T>

The same as bindSymbolOrNull but throws an error if symbol could not be bound

fun <T> Algebra<T>.bindSymbol(symbol: Symbol): T

bindSymbolOrNull

open fun bindSymbolOrNull(value: String): StructureND<T>?

Wraps a raw string to T object. This method is designed for three purposes:

bindSymbolOrNull

fun <T> Algebra<T>.bindSymbolOrNull(symbol: Symbol): T?

@PerformancePitfall

fun <T : Comparable<T>> AlgebraND<T, Ring<T>>.contentEquals(st1: StructureND<T>, st2: StructureND<T>): Boolean

Indicates whether some StructureND is equal to another one.

@PerformancePitfall

fun <T : Comparable<T>> GroupOpsND<T, Ring<T>>.contentEquals(st1: StructureND<T>, st2: StructureND<T>, absoluteTolerance: T): Boolean

Indicates whether some StructureND is equal to another one with absoluteTolerance.

open operator fun T.div(arg: StructureND<T>): StructureND<T>

Divides an element by an ND structure of it.

open operator fun StructureND<T>.div(arg: T): StructureND<T>

@UnstableKMathAPI

open fun export(arg: StructureND<T>): StructureND<T>

Export an algebra element, so it could be accessed even after algebra scope is closed. This method must be used on algebras where data is stored externally or any local algebra state is used. By default (if not overridden), exports the object itself.

@UnstableKMathAPI

open fun <F : StructureFeature> getFeature(structure: StructureND<T>, type: KClass<out F>): F?

Get a feature of the structure in this scope. Structure features take precedence other context features.

@UnstableKMathAPI

inline fun <T : Any, F : StructureFeature> AlgebraND<T, *>.getFeature(structure: StructureND<T>): F?

Get a feature of the structure in this scope. Structure features take precedence other context features.
