rewrote v as the identity matrix times v.
If these matrices are collectively the inverse matrix, if I do them, if I multiply the identity matrix times them-- the elimination matrix, this one times that equals that.
only if the 0 vector is equal to lambda times the identity matrix minus A times v.
you multiply it the other way, you would also get the identity matrix.
Now, we can rewrite v as-- v is just the same thing as the identity matrix times v, right? v is a member of Rn.
I have to get the identity matrix on the set X.
So this is equivalent to the matrix lambda times the identity matrix minus A times the vector v.
you get the identity matrix.
You multiply the identity matrix times an eigenvector
Lambda times-- instead of v I will write the identity matrix, the n by n identity matrix times v minus A times v is equal to the 0 vector.
if I multiplied the inverse matrix times the identity matrix, I will get the inverse matrix. .
this just gets reduced to the identity matrix.
we just take the identity matrix that has the standard basis vectors as columns.
the determinant of lambda times the identity matrix minus A is equal to 0.
Or if we could rewrite this as saying lambda is an eigenvalue of A if and only if-- I will write it as if-- the determinant of lambda times the identity matrix minus A is equal to 0.
and make sure that you get the identity matrix.
then this right here tells us that the determinant of lambda times the identity matrix, so it's going to be the identity matrix in R2.
If A is a given n×n matrix and In is the n×n identity matrix, then the characteristic polynomial of A is defined as p( λ) det( λ I n- A),{\displaystyle p(\lambda)=\det(\lambda I_{n}-A)~,} where det is the determinant operation and λ is a scalar element of the base ring.
C transpose times C, I get the identity matrix.
Or the columns in my identity matrix.
