Jul 16, 2013 at 8:29 | comment | added | Willie Wong | Is $n$ fixed? Meaning, are you asking whether there is a uniform bound for $\sum_{i =1}^n A_{1i}$ independent of $n$ (which I assume is the dimension of the matrix), or are you asking whether for each $n$ there is a bound which may depend on $n$? | |

Jul 16, 2013 at 8:00 | comment | added | Yemon Choi | @GottfriedHelms I read this as the usual partial order on the set of positive semi-definite matrices, so that one can take any PSD matrix X and put A = I + X / (100 r(X)) | |
