For example,ĪppleData="apple","color"->"red","weight"->100gram |> Īssociations can be generated by CountBy, GroupBy or PositionIndex (note that SortBy is another meaning. This is powerful and make the language more expressive. This works - however now there are a whole package of operations acting on associations, either on its values or keys. Previously, I use function rules to mimic association in Mathematica. , which works with a new type of data structure, similar to dictionary in Python and Map in C++ 11. Now there is a set of new functions - Association, Lookup, Keys, Values, KeyExistQ, CountBy. The on-going manual for Mathematica 10, or rather they uplift it to the Wolfram Language (interestingly, the non-GUI way to run Mathematica is now no longer "math", but "wolfram"), can be found on Wolfram's official site: But as of writing, the links inside here are not available yet. Sometime in the future there will be an official summary for the new features. The findings are based on a list of new functions, as pointed out in.
In the last blog post I introduced how to install Mathematica 10 in a virtual machine. Fortunately now some of them are no longer secret. I am quite curious about what's new in Mathematica 10.
