Question

How to find minimal polynomial of block diagonal matrices?

Answer 1

Step-by-step explanation:

To calculate the standard deviation for a sample of N measurements:

Sum all the measurements and divide by N to get the average, or mean.

Now, subtract this average from each of the N measurements to obtain N "deviations".

Square each of these N deviations and add them all up.

Divide this result by. (N − 1)

Answer 2

Step-by-step explanation:

But for a diagonal matrix, the minimal polynomial is just the product of factors x − λ, where λ runs through the distinct diagonal entries. (It is the monic polynomial of smallest degree that has all diagonal entries as roots.)
