Crash Posted September 20, 2005 Share Posted September 20, 2005 Im Having diffuculty in working out the nullity of a matrix, the matrix is a=[ 1,-1,1;-1,1,-1;1,-1,1] to find the nullity i was finding the eigenvalues and than working out the nullspace and than working out its dimension, is this correct? the other problem with this is i get to the polynomial equation from det(A-Lambda.I)=0 which ends up being -x^3 + 5x^2 -5x -1 which i dont think is correct, can someone please help. also can someone explain to me what multiplicity is?
