- LIBCONV, An SGI Optimized Library for Convolution and Correlation
-
-
-
- This PostScript file is a link to toolbox/lib/mathlib/libconv/doc. As of
- Version 3.1 of the Developer's Toolbox, libconv is a new addition to the
- math library subtree. From the introducion:
-
-
- Libconv is an optimized library available on Silicon Graphics computers.
- It features Convolution for Finite Impulse Response (FIR) and Infinite
- Impulse Response (IIR) filters, together with Correlations. The library
- modules take 1D and 2D inputs, and are available in single and double
- precision for real and complex arithmetic. The 2D subprograms have been
- parallelized and take full advantage of SGI parallel architecture.
-
- Section 1 presents the definitions used for Convolution and Correlation,
- 1D and 2D. Libconv implementation and conventions are explained in
- section 2. Examples of performance achieved by Libconv modules are
- presented in section 3.
-
- In the Appendix three short programs provide examples of practical usage
- of Libconv modules.
