| Apr 24, 2012 at 7:49 | comment | added | Federico Poloni | @Suvrit: for the negative ($-A$), rather than the inverse. I think "least" should be understood as "leftmost in the complex plane", otherwise the property does not hold for all Z-matrices as the OP claims. | |
| Apr 24, 2012 at 4:42 | comment | added | Suvrit | so this is in a sense, like a Perron-Frobenius property, but only for the least eigenvalues (so in a way, Perron-Frobenius for the inverse)... | |
| Apr 24, 2012 at 1:03 | comment | added | Gerhard Paseman | Since you asked, my uneducated and subjective opinion is that I don't think much of "minpositive". You might consider "firstQ" for eigenvectors in the first quadrant (first orthant actually) and then something like "minfirstQ" for the type of matrix which I find more descriptive. Then again, you might think as much of "minfirstQ" as I do of "minpositive". Gerhard "Matrices By Any Other Name..." Paseman, 2012.04.23 | |
