Yacas: Forskelle mellem versioner

Nuværende version fra 27. jul. 2024, 06:42

Yacas er akronym for Yet Another Computer Algebra System, er et frit Computer Algebra System (CAS).

Yacas anvendes i regning og matematik samt naturvidenskaber og ingiørvidenskaber.^[1] Yacas kan foretage symbolsk manipulation af matematiske udtryk.^[2]

Yacas er offentliggjort som GNU Lesser General Public License.

Der findes en interface til Yacas ved navn Ryacas.^[3]

Programmeringssprog

Yacas er skrevet i programmeringssproget C++^[4]

Historie

Yacas blev lanceret i 1999.^[5]

Features og kommanoer (uddrag)

Yacas kan bl.a.:^[6]^[7]

Anvendes som basal lommeregner
Beregne binominalkoefficienter (dette er et eksempel): Bin(10, 4)
Beregne permutationer (dette er et eksempel): Permutations({a,b,c})
Løse ligninger: solve(ligning,x)
Løse differentialligninger, [se tabel nedenfor] (dette er et eksmpel): OdeSolve( y + y == 0 )
Differentiere: D(funktion,x)
Integrere: Integrate(funktion,x)
Beregne vektorprodukt alias krydsprodukt: CrossProduct(u, v)
Beregne determinant af en matrix: Determinant(M)
Tegne funktioners grafer (2D såvel som 3D)
Yacas er et programerbart software^[8]

Yacas har flere kommandoer til fælles med andre programmer^[9]^[10] bl.a.: Mathematica,^[11] Maple,^[12]^[13] Xcas^[14] og GeoGebra^[15] samt med grafregnerne TI-89,^[16] TI-92, Voyage 200 og TI-Nspire.
