Functions

add

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

Element-wise addition.

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.

bindSymbol

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

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

bindSymbol

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?

contentEquals

@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.

export

@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.

getFeature

@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.

getFeature

@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.

invoke

@PerformancePitfall

open operator fun (T) -> T.invoke(structure: StructureND<T>): StructureND<T>

Element-wise invocation of function working on T on a StructureND.

map

@PerformancePitfall(message = "Very slow on remote execution algebras")

open fun StructureND<T>.map(transform: A.(T) -> T): StructureND<T>

mapIndexed

@PerformancePitfall(message = "Very slow on remote execution algebras")

open fun StructureND<T>.mapIndexed(transform: A.(index: IntArray, T) -> T): StructureND<T>
