2015-08-11 12:13:02 +0200 | commented answer | Error in computation of eigenvalues in Sage Thank you so much. This one is working except for the p.factor and is giving the following error p.factor() Traceback (click to the left of this block for traceback) ... NotImplementedError: Factorization of multivariate polynomials over non-fields is not implemented. How do I correct the error please. Thank you |

2015-08-10 16:54:52 +0200 | commented question | Error in computation of eigenvalues in Sage Q1 to Q4, omega,sigma,A1 to A3 and mu_v are characters in the matrix and the rest of the columns are zeros. and they are declared as follows var('sigma,omega,Q1,Q2,Q3,Q4,A1,A2,A3,mu_v') |

2015-08-10 11:04:26 +0200 | asked a question | Error in computation of eigenvalues in Sage Dear all, I am trying to compute the eigenvalues of the following matrix Unfortunately am getting the following error. When I try with numerical values however, I get eigenvalues. My problem involves a matrix with characters and I want to know the nature of the eigenvalues so that I may draw certain conclusions. What should I do in order to compute my eigenvalues without an error. Thank you for support. |
