st: How define an asymmetric matrix on .dta file as an asymmetric matrix in Stata? |

Dear statalist. I have fairly large asymmetric matrices (e.g. 200 by 200) from which I want to compute eigenvalues using the command: matrix eigenvalues r c = A Each of my asymmetric matrices are stored as separate .dta files and have the following general structure: A B C D A 0 0 1 0 B 2 0 0 1 C 3 1 0 2 D 1 0 2 0 How do I define each of these .dta files as the asymmetric matrix A so that Stata understands that the matrix in the .dta file is in fact an asymmetric matrix? As far as I can see, I need to do this in order to execute the command: matrix eigenvalues r c = A Is there a simple command/way to accomplish this? Thank you and kind regards, Erik. * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
