Interface BLAS1

All Known Implementing Classes:

AMAX, AMIN, ASUM, AXPY, CABS1, COPY, DOT, DOTC, DOTU, NRM2, ROT, ROTG, ROTM, ROTMG, SCAL, SDOT, SWAP

public interface BLAS1

Basic Linear Algebra Subprograms (BLAS) Level 1 contains vector operations.

• BLAS Level 1 @ WikipediA
• BLAS Level 1 @ Netlib
• BLAS Level 1 @ Intel

For each operation there should be 2 sets of implementations:

1. Optimised to be the implementations for the DenseArray instances.
2. Optimised to be building blocks for higher level algorithms
