Nested lists are lists within a list; they are the principal structure for data in the Wolfram Language and allow for high-dimension arrays and ragged ...

You can refer to an element of a Wolfram Language list by giving its "index". The elements are numbered in order, starting at 1.

Lists are central constructs in the Wolfram Language, used to represent collections, arrays, sets, and sequences of all kinds. Lists can have any structure and size and can routinely involve even millions of elements. Well over a thousand built-in functions throughout the Wolfram Language operate directly on lists, making lists a powerful vehicle for interoperability.

Position[expr, pattern] gives a list of the positions at which objects matching pattern appear in expr. Position[expr, pattern, levelspec] finds only objects that appear on levels specified by levelspec. Position[expr, pattern, levelspec, n] gives the positions of the first n objects found. Position[pattern] represents an operator form of Position that can be applied to an expression.

22.02.2019 · So I tried replacing the 949 value by: Position [SSpecWavelength, Subscript [\ [Lambda], G] [Eg_]]/.numval. So basically I try using Position to find the index at which the element in the list is equal to the wavelenght that I calculate based on an energy value. When I run it I get empty curly brackets.

It is sometimes useful to think of a nested list as being laid out in space, with each element at a coordinate position given by its indices.

We can instead use FirstPosition to avoid search the entire list. Now the time is 6 seconds. It's still not great. {# ...
