Functions

Other Functions

inner

inner($a, $b) – inner (dot) product along the first dimension.

matmult

matmult($a, $b [, $c]) — matrix multiplication.

append

append($a, $b) — concatenate two PDLs along dimension 0. Handles null PDL inputs: append(null, null) → empty, append(null, x) → x, etc.

interpol

interpol($xi, $x, $y) — linear interpolation. For each query point in $xi, find the corresponding y-value in the reference dataset ($x, $y). Mirrors upstream PDL::Primitive::interpol (Primitive.pd:3010) which delegates to interpolate($xi, $x, $y, $yi).

indexND

indexND($data, $indices) — index into data using N-D coordinate columns.

axisvalues

axisvalues($pdl) — fill PDL with index values along dim 0. Mirrors PDL::Primitive pp_def ‘axisvalues’ Code => ‘loop(n) %{ $a() = n; %}’ Supports inplace: axisvalues($pdl->inplace) modifies $pdl directly.

indadd

indadd($input, $ind, $sum) – broadcasting index-add.

uniqind

uniqind($pdl) — return flat indices of unique elements. Mirrors PDL::uniqind from Primitive.pm:727-756.

fibonacci

fibonacci($n_or_pdl) – Fibonacci sequence constructor.
