Det giver et tolket sprog, der i vid udstr\u00e6kning er kompatibelt med Matlab. GNU Octave kan bruges til at l\u00f8se line\u00e6re opgaver, ikke-line\u00e6re og differentialligninger, beregninger med komplekse tal og matricer, visualisering af data samt gennemf\u00f8relse af matematiske eksperimenter. Koden er skrevet i C++ (gr\u00e6nseflade p\u00e5 Qt) og distribueres under GPLv3-licensen.     <\/p>\n<p>Blandt \u00e6ndringerne i den nye udgave:  <\/p>\n<ul>\n<li class=\"l\"> Den pakkeadministrator pkg har f\u00e5et en ny kommando til at s\u00f8ge &#171;pkg search foo bar baz&#187;. I kommandoen &#171;pkg install&#187; er der implementeret automatisk genkendelse af, om den angivne parameter er en lokal fil, en URL eller et pakket navn. Der er tilf\u00f8jet lokal caching af pakke metadata og verifikation af de indl\u00e6ste pakker med SHA256-hash.\n<li class=\"l\"> Brugergr\u00e6nsefladen til filh\u00e5ndtering (File Browse) er opdelt i to faner &#8212; en til navigation i filsystemets indhold og den anden til at se og administrere alle filer, der er \u00e5bne i redakt\u00f8ren.\n<li class=\"l\"> I dialogboksen til fils\u00f8gning er der tilf\u00f8jet en liste over tidligere foretagne s\u00f8gninger, og muligheden for at s\u00f8ge efter filer efter flere m\u00f8nstre er blevet implementeret.\n<li class=\"l\"> I den grafiske gr\u00e6nseflade anvendes vektorikoner i SVG-format, og der er som standard leveret en indbygget kommandolinjegr\u00e6nseflade til Octave.\n<li class=\"l\"> Indstillingerne er blevet udvidet med muligheder for at deaktivere sk\u00e6rmsk\u00e6rmen og bruge den nuv\u00e6rende mappe, hvor editoren er startet, som standard i dialogboksen til \u00e5bning af filer.\n<li class=\"l\"> Udsendelsen til PDF-fil er blevet 25% hurtigere.\n<li class=\"l\"> I visualiseringen er underst\u00f8ttelsen af alfa-blanding forbedret p\u00e5 systemer med nye versioner af OpenGL.\n<li class=\"l\"> St\u00f8tten til objekter defineret med n\u00f8gleordet &#171;classdef&#187; er forbedret. Ved adgang til elementer i objektet via punkt (objekt.element) kontrolleres det nu f\u00f8rst, om der findes egenskaber med det angivne navn, og hvis egenskaben mangler &#8212; navne p\u00e5 metoder, hvilket svarer til adf\u00e6rden i MatLab.\n<li class=\"l\"> Udf\u00f8relsen af konvolutionsoperationer p\u00e5 arrays, hvor antallet af kolonner overstiger antallet af r\u00e6kker (vektormatricer), er v\u00e6sentligt accelereret (fra 10% til 150 gange afh\u00e6ngig af st\u00f8rrelse og form).\n<li class=\"l\"> Muligheden for at udf\u00f8re broadcasting-operationer p\u00e5 matricer af forskellige dimensioner er blevet tilf\u00f8jet for specialtyper af matriser, s\u00e5som sparse, diagonale og permuteringsmatricer. Desuden er der implementeret underst\u00f8ttelse af blandede operationer mellem sparse og fulde matricer samt diagonale matricer og almindelige vektorer.\n<li class=\"l\"> Der er foretaget \u00e6ndringer for at forbedre kompatibiliteten med Matlab. I funktionerne cumprod, cumsum, min, max, cummin, cummax, prod, sum, sumsq, bounds, center, meansq, range, statistics og zscore er der tilf\u00f8jet underst\u00f8ttelse af parametrene &#171;all&#187;, &#171;vecdim&#187; og &#171;nanflag&#187;.\n<li class=\"l\"> Ydeevnen for funktionerne sum, cumsum og sumsq er forbedret op til 6 gange. Funktionerne randi er blevet accelereret med op til 4,5 gange og hukommelsesforbruget er reduceret med op til 3,5 gange.\n<li class=\"l\"> I funktionen sum er der implementeret en \u00f8get pr\u00e6cisionsdrift. Pr\u00e6cisionen af beregningerne i funktionerne norm og fzero er forbedret.\n<li class=\"l\"> Funktionen roots og statistiske funktioner har f\u00e5et tilf\u00f8jet underst\u00f8ttelse for inddata af type double og single.\n<li class=\"l\"> Nye funktioner er blevet tilf\u00f8jet: _Exit, assert_equal, corrcov, dither, funm, mape, rms, rmse, trexc, xline og yline.        <\/ul>\n<p>                <center><img decoding=\"async\" alt=\"Udgivelse af GNU Octave 11, et system til matematiske beregninger\" src=\"\/wp-content\/uploads\/2026\/02\/84d476c4987fc96a0ed2d811847ca9ab.png\" style=\"display:block;margin: 0 auto;\" \/><\/center><br \/>\n<br \/>Kilde: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=64863\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0421\u043e\u0441\u0442\u043e\u044f\u043b\u0441\u044f \u0440\u0435\u043b\u0438\u0437 \u0441\u0438\u0441\u0442\u0435\u043c\u044b \u0434\u043b\u044f \u0432\u044b\u043f\u043e\u043b\u043d\u0435\u043d\u0438\u044f \u043c\u0430\u0442\u0435\u043c\u0430\u0442\u0438\u0447\u0435\u0441\u043a\u0438\u0445 \u0440\u0430\u0441\u0447\u0451\u0442\u043e\u0432 GNU Octave 11.1.0 (\u043f\u0435\u0440\u0432\u044b\u0439 \u0432\u044b\u043f\u0443\u0441\u043a \u0441\u0435\u0440\u0438\u0438 11.x, \u0432\u0435\u0442\u043a\u0430 11.0 \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u043b\u0430\u0441\u044c \u0434\u043b\u044f \u0440\u0430\u0437\u0440\u0430\u0431\u043e\u0442\u043a\u0438), \u043f\u0440\u0435\u0434\u043e\u0441\u0442\u0430\u0432\u043b\u044f\u044e\u0449\u0435\u0439 \u0438\u043d\u0442\u0435\u0440\u043f\u0440\u0435\u0442\u0438\u0440\u0443\u0435\u043c\u044b\u0439 \u044f\u0437\u044b\u043a, \u0432\u043e \u043c\u043d\u043e\u0433\u043e\u043c \u0441\u043e\u0432\u043c\u0435\u0441\u0442\u0438\u043c\u044b\u0439 \u0441 Matlab.
