Vector Programming

How to generate vector instructions?

Use vectorized library
Predefined vector operations (partially implemented in assembly language)
- VECLIB, LINPACK, EISPACK, MINPACK
```
C = SSUM(100, A(1,2), 1, B(3,1), N)
```
100 ...vector length

A(1,2) ...vector address A

1 ...vector stride A

B(3,1) ...vector address B

N ...vector stride B

Addition of matrix column to matrix row.
