Notes for CPSC

1. Performs $y \leftarrow \alpha x$
2. An index file input line looks like:

   <ID> <alpha> <incX> <incY> <source file> <author name>
   

3. Never called with $\alpha$ of zero (SET is called instead).
4. Never called with $\alpha$ of one (COPY is called instead).
5. For complex, if both vector strides are 1, and the imaginary component of $\alpha$ is zero, the real kernel is called with 2*N.
6. incX arbitrary incY=1 is interesting since it represents copying to contiguous storage.
