Hi I have been trying to extract the data from an eigenvectors() command to an Excel file. I have tried some basic writedata() commands but without luck. I´m guessing that the "strange" format of the output from the eigenvectors() command: [eigenvalue1, algebraicmultiplicator, [eigenvector1]], [eigenvalue2, algebraicmultiplicator, [eigenvector2]], and so forth is what is causing the problem. Does anyone know how I can do this?? Would mean alot to me if anyone does since it is eigenvalues and eigenvectors from an 31x31 matrix....ehhm :) Best regards Einar
