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.

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: C.(T) -> T): StructureND<T>

Maps elements from one structure to another one by applying transform to them.

mapIndexed

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

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

Maps elements from one structure to another one by applying transform to them alongside with their indices.

structureND

abstract fun structureND(shape: Shape, initializer: C.(IntArray) -> T): StructureND<T>

Produces a new StructureND using given initializer function.

unaryOperation

open fun unaryOperation(operation: String, arg: StructureND<T>): StructureND<T>

Dynamically invokes a unary operation with the certain name.

unaryOperationFunction

open fun unaryOperationFunction(operation: String): (arg: StructureND<T>) -> StructureND<T>

Dynamically dispatches a unary operation with the certain name.

zip

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

open fun zip(left: StructureND<T>, right: StructureND<T>, transform: C.(T, T) -> T): StructureND<T>

Combines two structures into one.

Extensions

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.

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.
