fun ForwardScalar(primal: DScalar, derivativeID: ForwardDerivativeID, tangent: DTensor)

Functions

get

open operator fun get(index: Int): DTensor

open operator fun get(vararg indices: Int): DTensor

toCodeString

open override fun toCodeString(): String

toString

open override fun toString(): String

wrap

Properties

derivativeID

open override val derivativeID: ForwardDerivativeID

Each derivative is assigned a unique DerivativeID

indices

open val indices: Iterator<IntArray>

An iterator over the indices for the tensor

isScalar

open val isScalar: Boolean

True if the tensor is a scalar.

operations

open override val operations: Operations

The operations available on a tensor.

primal

open override val primal: DScalar

primal points to the actual tensor

rank

open val rank: Int

The number of dimensions in the tensor's shape. rank 0 - Scalar rank 1 - 1D array or 1D tensor rank 2 - 2D matrix or 2D tensor rank 3 - 3D tensor ... rank N - ND tensor

shape

open val shape: Shape

shape indicates the number of dimension of a tensor and the length of each dimension. If the shape of the tensor is 3x4x5 then the value of shape is Shape(3,4,5).

size

open val size: Int

The total number of elements of this tensor.

tangent

open var tangent: DTensor
