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

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

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

mapIndexed

@PerformancePitfall

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

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

@JvmName(name = "oneVarArg")

fun <T, A : Ring<T>> AlgebraND<T, A>.one(shapeFirst: Int, vararg shapeRest: Int): StructureND<T>

structureND

open override fun structureND(shape: ShapeND, initializer: A.(IntArray) -> T): BufferND<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.

zero

fun <T, A : Group<T>> AlgebraND<T, A>.zero(shape: ShapeND): StructureND<T>

@JvmName(name = "zeroVarArg")

fun <T, A : Group<T>> AlgebraND<T, A>.zero(shapeFirst: Int, vararg shapeRest: Int): StructureND<T>

zip

@PerformancePitfall

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