    @bpf ## llll (required)
    @x ## int/float/list (required)
) -> int/float/list

Samples an interpolated value from a breakpoint function, given a list of normalized indices. See bpf function.

Arguments​

  • @bpf [llll]: Breakpoint function (required)
  • @x [int/float/list]: Sampling point/s (required)

Output​

Interpolated bpf values [int/float/list]

Usage​

$bpf = [0 1 0] [1 0 -0.25];
$x = arithmser(0, 1, null, 5); ## sampling points
$y = samplebpf($bpf, $x);
print($y)
