Efficient methods for operating on such matrices, often wrapping the 'BLAS', 'LAPACK', and 'SuiteSparse' libraries.https://github.com/r-universe/jaganmn/actions/runs/40086008834Fri, 24 Jul 2026 18:44:51 GMTMatrix1.8-0successhttps://jaganmn.r-universe.devhttps://codeberg.org/jaganmn/matrixIntro2Matrix.RnwIntro2Matrix.pdf2nd Introduction to the Matrix Package2026-06-26 05:24:182026-06-26 05:24:18Comparisons.RnwComparisons.pdfComparisons of Least Squares calculation speeds2026-06-26 05:24:182026-06-26 05:24:18Design-issues.RnwDesign-issues.pdfDesign Issues in Matrix package Development2026-06-26 05:24:182026-06-26 05:24:18Introduction.RnwIntroduction.pdfIntroduction to the Matrix Package2026-06-26 05:24:182026-06-26 05:24:18sparseModels.RnwsparseModels.pdfSparse Model Matrices2026-06-26 05:24:182026-06-26 05:24:18jaganmn2@gmail.com (Mikael Jagan)An R interface to 'FLINT' <https://flintlib.org/>, a C library for number theory. 'FLINT' extends GNU 'MPFR' <https://www.mpfr.org/> and GNU 'MP' <https://gmplib.org/> with support for operations on standard rings (the integers, the integers modulo n, finite fields, the rational, p-adic, real, and complex numbers) as well as matrices and polynomials over rings. 'FLINT' implements midpoint-radius interval arithmetic, also known as ball arithmetic, in the real and complex numbers, enabling computation in arbitrary precision with rigorous propagation of rounding and other errors; see Johansson (2017) <doi:10.1109/TC.2017.2690633>. Finally, 'FLINT' provides ball arithmetic implementations of many special mathematical functions, with high coverage of reference works such as the NIST Digital Library of Mathematical Functions <https://dlmf.nist.gov/>. The R interface defines S4 classes, generic functions, and methods for representation and basic operations as well as plain R functions mirroring and vectorizing entry points in the C library.https://github.com/r-universe/jaganmn/actions/runs/40081543352Wed, 22 Jul 2026 13:38:01 GMTflint0.1.6successhttps://jaganmn.r-universe.devhttps://codeberg.org/jaganmn/flint
