If there is a jordan block matrix with A(i,i) = a for all i=1 to n, A(i,i+1)=b for all i=1 to n-1 and A(j,k)=0 otherwise. What will be eigen value and eigen vector of J.
To calculate evalues I split the matrix in a Diagonal matrix = diag(a) and another matrix B with A(i,i+1)=b. As B is singular matrix, one of the evalues will be zero. So for Jordan block matrix evalue become =a+0 =a. How to find rest of the evalues and evectors.
