Filling the matrix entries

1 次查看(过去 30 天)
I have a matrix to deal with.
A=[1 2 3 4 5 6 7;4 6 7 4 5 8 7; 6 7 8 9 3 5 6];
for i=1:3
A(i,i)=0;
end
In the above simple code I could change A(i,i) by 0. Now I want to start from the last entry(A(3,7)) and change to 0 in the similar way. In simple way A(3,7), A(2,6,) and A(1,5) should be changed by zero. I need it in the loop I started.

Perhaps this:
A=[1 2 3 4 5 6 7;4 6 7 4 5 8 7; 6 7 8 9 3 5 6]
A = 3×7
1 2 3 4 5 6 7 4 6 7 4 5 8 7 6 7 8 9 3 5 6
for k = 1 : 3
A(k, k+4)=0;
end
A % Display result
A = 3×7
1 2 3 4 0 6 7 4 6 7 4 5 0 7 6 7 8 9 3 5 0
