Type Properties
static var zero: Array<Element>.DifferentiableViewThe zero value.
Instance Properties
var base: [Element]The viewed array.

var description: StringA textual representation of this instance.
Instance Methods
func move(by: Array<Element>.DifferentiableView.TangentVector)Moves
selfby the given offset. In Riemannian geometry, this is equivalent to exponential map, which movesselfon the geodesic surface by the given tangent vector.func move(by: Self.TangentVector)Moves
selfby the given offset. In Riemannian geometry, this is equivalent to exponential map, which movesselfon the geodesic surface by the given tangent vector.
Type Operators
static func != (Self, Self) -> Boolstatic func + (Self) -> SelfReturns the given number unchanged.
static func + (Array<Element>.DifferentiableView, Array<Element>.DifferentiableView) -> Array<Element>.DifferentiableViewAdds two values and produces their sum.
static func += (inout Self, Self)Adds two values and stores the result in the left-hand-side variable.
static func - (Array<Element>.DifferentiableView, Array<Element>.DifferentiableView) -> Array<Element>.DifferentiableViewSubtracts one value from another and produces their difference.
static func -= (inout Self, Self)Subtracts the second value from the first and stores the difference in the left-hand-side variable.
static func == (Array<Element>.DifferentiableView, Array<Element>.DifferentiableView) -> BoolReturns a Boolean value indicating whether two values are equal.
