Ipaper.duplicated — Function
duplicated(x::Vector{<:Real})
x = [1, 2, 3, 4, 1]
duplicated(x)
# [0, 0, 0, 0, 1]
source
Ipaper.list — Function

Ipaper.match2 — Function
match2(x, y)

Examples

## original version
mds = [1, 4, 3, 5]
md = [1, 5, 6]

findall(r_in(mds, md))
indexin(md, mds)

## modern version
x = [1, 2, 3, 3, 4]
y = [0, 2, 2, 3, 4, 5, 6]
match2(x, y)

Note: match2 only find the element in y
