Enumeration Type Documentation

◆ BLAS_Layout

enum sdfg::math::blas::BLAS_Layout

Memory layout for BLAS matrices.

Specifies how matrix elements are stored in memory:

  • RowMajor: Rows are contiguous (C-style, 101)
  • ColMajor: Columns are contiguous (Fortran-style, 102)
Enumerator
RowMajor 
ColMajor 

◆ BLAS_Precision

enum sdfg::math::blas::BLAS_Precision

Precision/data type for BLAS operations.

Indicates the floating-point precision of the operation:

  • h: Half precision (16-bit)
  • s: Single precision (32-bit float)
  • d: Double precision (64-bit double)
  • c: Complex single precision
  • z: Complex double precision
Enumerator

◆ BLAS_Transpose

enum sdfg::math::blas::BLAS_Transpose

Transpose operation for BLAS matrices.

Specifies whether to use a matrix as-is or transposed:

  • No: No transpose (111)
  • Trans: Transpose (112)
  • ConjTrans: Conjugate transpose (113)
Enumerator
No 
Trans 
ConjTrans
