Comparison (PR#56 vs master)

A ratio greater than 1.0 denotes a possible regression (marked with ❌), while a ratio less than 1.0 denotes a possible improvement (marked with ✅). Only significant results - results that indicate possible regressions or improvements - are shown below (thus, an empty table means that all benchmark results remained invariant between builds).

ID time ratio memory ratio
["inrange", "NearestNeighbors.KDTree 3 × 1000, ls = 1, input_size = 1000, r = 1.91e-01"] 0.92 (5%) ✅ 1.00 (1%)

With SecureCRT closed, edit your Global.ini which lives by default in %appdata%\VanDyke\Config\Global.ini,
find the three lines the start with B:"ANSI Color RGB" and replace it and the two lines of hex below it with:
B:"ANSI Color RGB"=00000040
00 2b 38 00 dc 32 2f 00 85 99 00 00 b5 89 00 00 26 8b d2 00 d3 36 82 00 2a a1 98 00 ee e8 d5 00

O(n) functions for computing cumulative estimates of some basic statistics (useful e.g. for plotting how these estimates evolve).
cummean(x) = cumsum(x) ./ [1:length(x)]
cumvar(x, m = cummean(x)) = cumsum((1 - 1 ./ [1:length(x)]).*(x - [0, m[1:end-1]]).^2) ./ [1:length(x)]
cumcov(x, y, mx = cummean(x), my = cummean(y)) = cumsum((1 - 1 ./ [1:length(x)]).*(x - [0, mx[1:end-1]]).*(y - [0, my[1:end-1]])) ./ [1:length(x)]
