FillArrays.FillArrays — Module

FillArrays module to lazily represent matrices with a single value

source
FillArrays.AbstractFill — Type
AbstractFill{T, N, Axes} <: AbstractArray{T, N}

Supertype for lazy array types whose entries are all equal. Subtypes of AbstractFill should implement FillArrays.getindex_value to return the value of the entries.

source
FillArrays.Falses — Type
Falses = Zeros{Bool, N, Axes}

Lazy version of falses with axes.

See also: Trues

source
FillArrays.Fill — Type
Fill{T, N, Axes} where {T,N,Axes<:Tuple{Vararg{AbstractUnitRange,N}}}

A lazy representation of an array of dimension N whose entries are all equal to a constant of type T, with axes of type Axes. Typically created by Fill or Zeros or Ones

Examples

julia> Fill(7, (2,3))

FillArrays.OneElement — Type
OneElement(val, ind, axesorsize) <: AbstractArray

Represents an array with the specified axes (if its a tuple of AbstractUnitRanges) or size (if its a tuple of Integers), with a single entry set to val and all others equal to zero, specified by ind`.

source
FillArrays.OneElement — Method
OneElement(val, ind::Int, n::Int)

Creates a length n vector where the ind entry is equal to val, and all other entries are zero.

FillArrays.Trues — Type
Trues = Ones{Bool, N, Axes} where {N, Axes}

Lazy version of trues with axes. Typically created using Trues(dims) or Trues(dims...)

FillArrays.fillsimilar — Method
fillsimilar(a::AbstractFill, axes...)

creates a fill object that has the same fill value as a but with the specified axes. For example, if a isa Zeros then so is the returned object.

FillArrays.getindex_value — Method
getindex_value(A::OneElement)

Return the only non-zero value stored in A.

Note

If the index at which the value is stored doesn't lie within the valid indices of A, then this returns zero(eltype(A)).
