Dear Kolja and Frederik,

Thanks in advance again! -- Luis Στις 04/04/12 18:57, ο/η Luis Peñaranda έγραψε:

Hello, I am trying to compute the adjoint of a matrix, but Eigen 3.0.5 gives me a result I am not expecting. To illustrate this, I reduced the issue to the attached code. I understand "adjoint" as the traspose of the cofactor matrix. In the attached example, the adjoint would be (checked with Maple): -3 6 -3 6 -12 6 -3 6 -3 But Eigen gives me the transpose of my input matrix: 1 4 7 2 5 8 3 6 9 So the question is, does Eigen use another definition for adjoint, am I making a mistake in my code or is this a bug? Thanks in advance for your answer,
