New Language Features

• matrix type
  • matrix[Rows, Columns]Element_Type
  • A matrix is a mathematical type built into Odin. It is a regular array of numbers, arranged in rows and columns
  • Multiplication between matrices and arrays
  • Component-wise operations
  • Submatrix casting square matrices
  • Submatrix casting non-square matrices
  • Column-major memory layout
  • Limited to a maximum of 16 elements
  • Supports integers, floats, and complex numbers (only)
  • Optimized for SIMD vectorization
  • Built-in procedures (Compiler Level)
    • transpose
    • outer_product
    • hadamard_product
    • matrix_flatten
    • conj
  • Built-in procedures (Runtime Level)
    • determinant
    • adjugate
    • inverse
    • inverse_transpose
    • hermitian_adjoint
    • matrix_trace
    • matrix_minor
• odin report
  • Reporting of Platform Specific Information
• wasi_wasm32 support
• Improved WASM support in general
