Web11 de abr. de 2024 · There are three scoping constructs used in Mathematica to localize variables -- Module, Block and With. Loop can be terminated using one of the following commands: Throw, Catch, Break, Continue, Return, Interrupt, and Abort. Module does lexical scoping (localizing names). Block does dynamic scoping (localizing values). i = 1; Web1. @Numth @Calle @whuber: Mathematica make the summation index local using Block. In this way k has a local value for the Sum function. However, k is still k so that g [k-1] translates into Sum [Binomial [k-1,k], {k,0,k-1}] which will evaluate to 0 (because Binomial [k-1,k]=0). What you want is that the summation index gets a different name and ...
