BLAS and Sparse BLAS Routines

Intel® oneAPI Math Kernel Libraryimplements the BLAS and Sparse BLAS routines, and BLAS-like extensions. The routine descriptions are arranged in several sections:

• BLAS Level 1 Routines (vector-vector operations)
• BLAS Level 2 Routines (matrix-vector operations)
• BLAS Level 3 Routines (matrix-matrix operations)
• Sparse BLAS Level 1 Routines (vector-vector operations).
• Sparse BLAS Level 2 and Level 3 Routines (matrix-vector and matrix-matrix operations)
• BLAS-like Extensions

The question mark in the group name corresponds to different character codes indicating the data type (s, d, c, and z or their combination); see Routine Naming Conventions.

When BLAS or Sparse BLAS routines encounter an error, they call the error reporting routine xerbla.
