How to assign values in an identity matrix?

5 次查看(过去 30 天)
Simple question, but say I have a 3x3 identity matrix:
I = eye(3)
I =
1 0 0
0 1 0
0 0 1
And I want to change the upper right two elements to, say, 2 and 4:
I =
1 0 2
0 1 4
0 0 1
Is there a function that will allow me to do this?

For this specific question, simple indexed assignment:
I(1:2,end) = [2;4];
But what is your actual problem?
