Hi,

I have a probelm in finding eigenvectors. For example, we have a matrix:

1 2

3 2

The eignevalues for this are x = -1 and x = 4. I understand how to find the eigenvector when x = -1. But when x = 4, we get:Code:

-3 2 y 0

* =

3 -2 z 0

which, when multiplied by means that 3y - 2z = 0 (using (A-xI)v=0). Now the final answer is:Code:

2y

v =

3y

How??
