invers matriks 3x3 dengan python.
ini merupakan codingan program saya dengan python baris1=[-8,-1,-3] baris2=[6,-9,6] baris3=[7,8,3] print(baris1) print(baris2) print(baris3) det = (baris1[0]*baris2[1]*baris3[2] + baris1[1]*baris2[2]*baris3[0] + baris1[2]*baris2[0]*baris3[1] - baris3[0]*baris2[1]*baris1[2] - baris3[1]*baris2[2]*baris1[0] - baris3[2]*baris2[0]*baris1[1]) print("Hasil Determinan Matriks:",det) a11 = baris2[1]*baris3[2] - baris2[2]*baris3[1] a12 = (-1*((baris2[0]*baris3[2]) - (baris2[2]*baris3[0]))) a13 = baris2[0]*baris3[1] - baris2[1]*baris3[0] a21 = (-1*((baris1[1]*baris3[2]) - (baris1[2]*baris3[1]))) a22 = baris1[0]*baris3[2] - baris1[2]*baris3[0] a23 = (-1*((baris1[0]*baris3[1]) - (baris1[1]*baris3[0]))) a31 = baris1[1]*baris2[2] - baris1[2]*baris2[1] a32 = (-1*((baris1[0]*baris2[2]) - (baris1[2]*baris2[0]))) a33 = baris1[0]*baris2[1] - baris1[1]*baris2[0] print("\nHasil Kofaktor Matriks:") print("|",a11,a12,a13,"|") print("|...
