toolbox/documents/libconv README 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.
