Committed by thanos

Commit Message

closed #139 - Complete Multi-dimensional Array Indexing
✅ Completed Features

  1. Basic Slicing with Enhanced Features

  - Full multi-dimensional slicing
  - Step support (positive steps: 1, 2, 3, 5, etc.)
  - Map format: start: %{0 => 0}, stop: %{0 => 10}, step: 2
  - Empty slice handling
  - Edge case validation

  2. Fancy Indexing

  - get_fancy/2 - integer array indexing (vindex)
  - get_orthogonal/2 - Cartesian product indexing (oindex)
  - Negative index support

  3. Boolean Indexing

  - get_boolean/2 - mask-based selection
  - 1D and 2D mask support
  - Validation of mask size and type

  4. Block Indexing

  - get_blocks/2 - chunk-aligned access
  - Efficient multi-chunk operations

  5. Array Manipulation

  - resize/2 - grow or shrink dimensions
    - Returns {:ok, updated_array}
    - Handles fill values for new space
    - Deletes out-of-bounds chunks when shrinking
  - append/3 - add data along axis
    - Returns {:ok, updated_array}
    - Efficient chunk-aligned appends

  6. Return Type Consistency

  - get_slice/2 returns nested tuples (not binary)
  - All indexing functions return tuples
  - Proper dtype decoding
