From 9ac43d224e09e0cf3c9be9ba8f3bbbaca2dcbbc9 Mon Sep 17 00:00:00 2001 From: Benjamin Date: Fri, 2 Oct 2026 13:13:31 +0200 Subject: [PATCH] feat: add C implementation for blas/ext/base/ndarray/dcartesian-product Add the ndarray C adapter, Node-API bridge and Fortran-aware native build metadata. Preserve the JavaScript fallback and cover Cartesian ordering, column-major layouts, strides, offsets and special values in native parity tests.

+ +### Usage + +```c +#include "stdlib/blas/ext/base/ndarray/dcartesian_product.h" +``` + +#### stdlib_blas_ext_dcartesian_product( arrays ) + +Computes the Cartesian product for two double-precision floating-point ndarrays and stores each pair in a row of a two-dimensional output ndarray. + +The function accepts the following arguments: + +- **arrays**: `[in] struct ndarray**` list containing two one-dimensional input ndarrays and a two-dimensional output ndarray. + +```c +void stdlib_blas_ext_dcartesian_product( const struct ndarray *arrays[] ); +``` + +
+ + + +
+ +### Notes + +- For inputs of lengths `M` and `N`, the output ndarray should have shape `[M*N, 2]`. +- The first column contains elements from the first input and the second column contains elements from the second input. +- If `M <= 0` or `N <= 0`, the output ndarray is unchanged. +- C ndarray strides and offsets are specified in bytes. The function supports independently strided input and output views. + +
