template <class Real> math::blas

File: BASE/math/Blas.H

Wrapper for BLAS (Basic Linear Algebra Subroutines)
BLAS (Basic Linear Algebra Subprograms) wrapper for inter-platform compatibility
supports: zcopy, zscal, zaxpy, zdotc supports only std::complex versions
Provides four versions, determined by the BLAS macro:
1. Generic, written with for-loops. BLAS undefined, or non float/double
2. IRIX blas and scsl_blas: defined(BLAS_IRIX)
3. IRIX older version: defined(BLAS_IRIX_OLD)
4. Linux version: defined(BLAS_LINUX)
