Find dimension and ker of matrices ??
Let V be an F-vector space and (phi:v->v) be an F-linear transformation of V . Define what
it means for a vector v ε V to be an eigenvector of phi and what is meant by the associated
eigenvalue.
This is the form of the question during my calculations I need to calculate:
Now I have from the eigenvalues:
dim(ker()) of a matrix:
1 4 -3
0 0 0
0 0 0
and
dim(ker()) of a matrix:
1 0 -2/7
0 1 -5/7
0 0 0
Then when the I add up the the dim's I will be able to tell if it is diagonalisable.
Now in this case it is obvious, the dim(ker()) of one is 1 and another is 2. But I can't tell which one is which.
What I mean is the 1st Matrix = 2 and the second Matrix = 1 or viceversa ?
In this case in either way it will add upto 3 and as the original matrix was a 3x3 matrix it is diagonalisable right ?
In essence I don't really understand what dim or ker do ...
