Dear all, I have a problem to calcute a matrix p(A) with p(x) is a polynomial of degree n with real koefficient and A is a matrix of size n time n. For an example: p(x)=x^2 +3x + 2 and then p(A)=A^2+3A+2I, with I is identity matrix of size 2 time 2. Thank you in advanced Subiono -- http://www.its.ac.id
