Mavzu: Matrisalarning asosiy xarakteristikalarini xisoblash
Masalaning qo’yilishi: Matlabda matritsalarni chapdan o’ngga burishda fliplr komandasidan foydalanish:
A=[-1 0 1; 0 -1 0; 1 -1 1]

1-rasm. A matritsa yaratdik

2-rasm. fliplr(A) buyrug’i orqali matrit chapdan o’ngga burishda sonlarni ekranga chiqardik
Endi shu komandani qo’lda bajarib chiqamiz:
>> for i=1:3; for j=1:3; C(i,j)=A(3-i+1,j);end; end; C



3-rasm. Bu matrisani qo’lda bajardik va
>> for i=1:3; for j=1:3; C(i,j)=A(3-i+1,j);end; end; C shu kodni ekranga chiqard
4-rasm. Buda esa yuqoridan pastga burishda flipud(A) komandasidan foydalandik.
Endi shu amalni algoritmi bilan tanishib chiqamiz:
>> for i=1:3; for j=1:3; C(j,i)=A(j,3-i+1); end; end; C



5-rasm. Bu rasmda A matrisani algoritm ko’rinishi

6-rasm. Bu rasmda matritsani soat strelkasiga qarshi 90 0 ga burish uchun ishlatiladigan rot90(A) komandasidan foydalandik.
Endi shu amalning bajarilish tartibi ya’ni algoritmi haqida ko’rib chiqamiz:
>> for i=1:3; for j=1:3; C(i,j)=A(j,3-i+1); end; end; C

7-rasm. Matrisani 90 ga burgandagi algortim ko’rinishida ekranga chiqardik.

ans =

1 -1 1
0 -1 0

for i=1:3; for j=1:3; C(j,i)=A(j,3-i+1); end; end; C

C =

1 0 -1
0 -1 0
