WebFilterRules is particularly practical since you may also use it with a rule b->something, even blank as second argument or with a list of such rules. In this case, it does not care for the rhs of those rules. – Adalbert Hanßen Apr 11, 2016 at 18:11 Add a comment 11 WebBUILT-IN SYMBOL Select Select Select [ list, crit] picks out all elements e i of list for which crit [ e i] is True. Select [ list, crit, n] picks out the first n elements for which crit [ e i] is True. Select [ crit] represents an operator form of Select that can be applied to an expression.

WebThe two basic types of transformation rules in the Wolfram Language. Replacements for pattern variables that appear in transformation rules are effectively done using ReplaceAll (the /. operator). WebJan 30, 2016 · Try this: a*b /. {a -> a, a -> 1, b -> c}. The first replacement just replaces a with a, but since that expression has already been changed, it is ignored after that, so the Rule a - > 1 is only applied to other parts of the expression, and there are no more a 's, but b gets replaced with c. So you're kind of right and kind of not. WebMap a Function over a List. The Wolfram Language includes many powerful operations for working with lists. It is often desirable to map a function onto each individual element in a list. While listable functions do this by default, you can use Map to do this with non-listable functions.
