Robustness & Error Handling—Wolfram Language Documentation

WebUsing the pattern-matcher to simplify the error-handling code One of the main mechanisms has been already described in the answer by @Verbeia - use the relative generality of the patterns. With regards to this, I can point to e.g. this package where I used this technique a lot, as an additional source for working examples of this technique. WebApr 18, 2015 · $\begingroup$ I don't know much about Maple, but it seems from your examples that it's less "careful" when simplifying expressions: Mathematica leaves expressions unevaluated if it can't get a result that's valid generically or consistent with the given assumptions. So probably one would have to allow an additional Assumptions … WebSo although not quite in the format required in the question, but something like this is possible: expression = a^2*b; expression /. {a -> Around [aval, da], b -> Around [bval, db]} output: aval^2 bval ± Sqrt [aval^4 db^2+4 bval^2 Abs [aval da]^2] Instead of aval, bval, da, db you can use numerical values as well. how can i secure an oar to a towel bar
