Plotting a histogram
This can be done by computing a histogram in Futhark and then using a box plot. Here we produce some arbitrary values, discretised aong k bins.
def plot k n : ([]i64,[]i32) =
let vs = iota n |> map (f64.i64 >-> f64.cos >-> (+1) >-> (*(f64.i64 k/2)) >-> i64.f64)
in (iota k,
hist (+) 0 k vs (replicate n 1))> :gnuplot {data=plot 100 10000};
set xrange [0:100];
set style fill solid 1.0
