MATLAB da kvadrat matritsalarning determinantini hisoblash uchun det buyrug’idan foydalaniladi. Masalan:

>> A2=[5 3; 2 8]
A2 =
5 3
2 8
>> det(A2)
ans =
34
K=[2 3 6 ; 1 8 4; 3 6 7]
K =
2 3 6
1 8 4
3 6 7
>> det(K)
ans =
-29
>> K4=[2 3 6 14; 1 8 3 7; 9 6 7 5; 1 2 8 9]
K4 =
2 3 6 14
1 8 3 7
9 6 7 5
1 2 8 9
>> det(K4)
ans =
3250
MATLAB da kvadrat matritsalarning determinantini hisoblash uchun det buyrug’idan foydalaniladi. Masalan:
>> A2=[5 3; 2 8]
A2 =
5 3
2 8
>> inv(A2)
ans =
0.2353 -0.0882
-0.0588 0.1471
>> K4=[2 3 6 14; 1 8 3 7; 9 6 7 5; 1 2 8 9]
K4 =
2 3 6 14
1 8 3 7
9 6 7 5
1 2 8 9
MATLAB da kvadrat matritsalarning teskarisini hisoblash uchun inv buyrug’idan foydalaniladi. Masalan:
>> inv(K4)
ans =
0.0892 -0.0865 0.1160 -0.1360
-0.0769 0.1538 0 0
-0.1477 -0.0086 0.0080 0.2320
0.1385 -0.0169 -0.0200 -0.0800
Bundan tashqari, matritsalarni transponerlash, rangi va normasini topish mumkin.
