Julia version of padarray in matlab

New to Julia

One way is from here:

julia> using Pkg; pkg"add ImageFiltering"

julia> using ImageFiltering

julia> arr = reshape(1:6, (2,3))
2×3 reshape(::UnitRange{Int64}, 2, 3) with eltype Int64:
 1  3  5
 2  4  6

julia> BorderArray(arr, Pad((1,1)))
4×5 BorderArray{Int64,2,Base.ReshapedArray{Int64,2,UnitRange{Int64},Tuple{}},Pad{2}} with indices 0:3×0:4:
 1  1  3  5  5
 1  1  3  5  5
 2  2  4  6  6
 2  2  4  6  6

Note that this won’t in general agree with the result of repeat, e.g.:

julia> repeat(arr, inner=[2,2])
4×6 Array{Int64,2}:
 1  1  3  3  5  5
 1  1  3  3  5  5
 2  2  4  4  6  6
 2  2  4  4  6  6

Note also that for padding with a constant, but not with the edge values, there is GitHub - JuliaArrays/PaddedViews.jl: Add virtual padding to the edges of an array
