The Utah Raster Toolkit is a collection of graphics tools ca. 1992. It is similar in purpose to the more widely known Netpbm/Pbmplus tools, but is based on a different basic format. The basic format for the Utah tools is RLE (named after "run length encoding"). The package contains converters between RLE and several other graphics file formats and Netpbm contains facilities to convert between RLE and lots of other formats. The collection includes programs that operate on files, a C subroutine library, and programs to display graphics on a various devices. The Utah Raster Toolkit is primarily the result of research work at The University of Utah and The University of Michigan.
MatLisp is a set of CLOS classes for handling matrices. The classes allow a simple and consistent interface to matrix operations. Matlisp is powered by the well-known and well-tested linear algebra packages BLAS and LAPACK, which provide the Matlisp user an immediate interface to a set of specialized and well-documented linear algebra routines such as +, -, *, /, eigenvalue, SVD, Cholesky decompositions and more.
