Math Workspace Monorepo

Packages for scientific computing in Dart.

Repository Structure

The repository is structured as a standard Dart workspace monorepo under pubspec.yaml:

• pkgs/num_dart: The core scientific tensor package. It supports n-dimensional arrays (NDArray), universal element-wise ufuncs, advanced multidimensional stride slicing, logical reductions, and Marsaglia-RNG distributions.
• pkgs/openblas: Minimalistic FFI bindings layer wrapping OpenBLAS cblas and LAPACK headers. Includes compile hooks to build OpenBLAS from source tarballs.
• pkgs/pocketfft: Native FFI wrappers around KissFFT mixed-radix discrete Fourier transform plans.

Development Guidelines

1. Packages Resolution

To fetch dependencies and prepare the workspace for all packages at once:

dart pub get

2. Code formatting & Analyzer

Ensure formatting and analyzer guidelines pass perfectly before pushing to a pull request:

dart format .
dart analyze

3. Executing Unit Tests

To run all tests from the root workspace folder:

dart test pkgs/*

4. Generating Coverage Reports

To measure test coverage metrics inside num_dart, navigate to pkgs/num_dart and run:

dart tool/generate_coverage.dart
