GNU Octave yog hom lus siab, feem ntau yog npaj rau kev suav lej. Nws muab ib qho yooj yim hais kom ua kab interface rau kev daws teeb meem linear thiab nonlinear tus lej, thiab rau kev ua lwm yam kev sim lej siv hom lus uas feem ntau sib xws nrog Matlab. Nws kuj tseem siv tau los ua ib hom lus hais lus.

Octave muaj cov cuab yeej dav siv los daws cov teeb meem ntawm cov lej linear algebra, nrhiav cov hauv paus ntawm cov kab zauv uas tsis yog kab sib npaug, sib xyaw ua haujlwm zoo tib yam, tswj cov zauv, thiab sib xyaw ua ke sib txawv sib txawv thiab sib txawv-algebraic sib npaug. Nws yog qhov yooj yim txuas ntxiv thiab kho tau los ntawm cov neeg siv cov haujlwm uas tau teev tseg hauv Octave tus kheej cov lus, lossis siv cov khoom siv hluav taws xob dynamically sau hauv C ++, C, Fortran, lossis lwm yam lus.
