By the way, SingularValueList returns a sorted list, so you can use First@#/Last@#&. Jul 17 comment How to estimate the matrix condition number in the 2-Norm? Interestingly, though it appears in blue, LinearAlgebraMatrixConditionNumber works (with the same problem as OP) Jul 17 comment How to estimate the matrix condition number in the 2-Norm? The former doesn't work for me in Mathematica 10. Did you need to import anything for it to work? Jul 17 awarded Commentator Jul 17 comment How to estimate the matrix condition number in the 2-Norm? You can compute it yourself with Norm[mat,2]Norm[Inverse@mat,2], but this is unsatisfying... Jul 14 accepted Equivalent of ReplaceAll for Associations? Jul 14 comment Equivalent of ReplaceAll for Associations? Actually...is that even documented? Jul 14 comment Equivalent of ReplaceAll for Associations? It's cool that functions like ^ work on the association's values. Jul 14 comment Equivalent of ReplaceAll for Associations? Neat. The really interesting part of this isn't that adding a key replaces an existing one, but that you can merge by putting the whole association inside another like <|#, ...|>`.
