Many computations are conveniently specified in terms of applying functions in parallel to many elements in a list. The Wolfram Language provides a suite of elegant functional programming constructs for doing this. In the Wolfram Language, mathematical functions are automatically taken to be "listable", so that they are always applied to every element in a list.

In Mathematica, you do not need to declare an empty list and then fill each element in with the desired value one by one. For example, typical procedural programming will create an empty vector, and replace each element in turn to create the desired data. vec = Table[0, ...

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 ...

16.01.2018 · Consider a list as list={1,2,3,4}; I can repeat the list n times in this way listRepeated=Flatten@Table[list, n]; Question 1: Can it be done in a faster way? I also want to repeat each element n

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 ...

The Wolfram Language provides a suite of elegant functional programming constructs for doing this. In the Wolfram Language, mathematical functions are automatically taken to be "listable", so that they are always applied to every element in a list. Map ( /@) — map a function over a list, at specified levels.

Create Lists. Lists are very important and general structures in the Wolfram Language. They allow you to treat collections of all kinds of objects as a single entity. There are many ways to construct them. Use the shorthand notation { } to make a list: Copy to clipboard. Or use List, which automatically is changed to { }: Copy to clipboard.

Lists are very important structures in the Wolfram Language . Lists allow you to treat any kind of collection of objects as a single entity.

13.12.2011 · I have a list and I want to apply a logical test to each element, and if any one of them does not satisfy this condition, then return false. I want to write this in Mathematica or find a built-in function, but seems ForAll does not actually do that.. My question is: …

The following function avoids the ugliness by converting pattern to body for each element of list . SetAttributes[ForEach, HoldAll]; ForEach[ ...

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.

1 day ago · I have a list of 400 elements and each element is a list of 3 other elements. how can I take the first element of all of 400 elements? for instance, how can I take elements a,d and g from the following list? list1 = { {a, b, c}, {d, e, f}, {g, h, i}} list-manipulation dataset elements. asked 4 mins ago. Sara Gholamhoseinian.

Perform Operations on Lists. Lists are central constructs in the Wolfram Language that are used to represent collections, arrays, sets, and sequences of all kinds. Well over a thousand built-in functions throughout the Wolfram Language operate directly on lists, making them a powerful vehicle for interoperability.

Additional test cases. In this example, we transform a list of variables: a = 1; b = 2; c = 3; each [i_, {a,b,c}, i = f [i]] After the above, {a,b,c} should evaluate to {f [1],f [2],f [3]}. Note that that means the second argument to each should be held unevaluated if it's a list. If the unevaluated form is not a list, it should evaluate the ...

Lists are central constructs in the Wolfram Language that are used to represent collections, arrays, sets, and sequences of all kinds. Well over a thousand built-in functions throughout the Wolfram Language operate directly on lists, making them a powerful vehicle for interoperability.

There are several constructs you can use. The one that comes closest to the foreach of other languages is a = {1, 2, 3}; Do[Print[i], {i, ...

Map 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. First set up a list of the integers from 1 to 5:

The elements of each inner list correspond to successive values of , with fixed. ... "Linear Algebra in Mathematica" discusses many other matrix operations ...

Get Elements of Lists. Lists are very important structures in the Wolfram Language. Lists allow you to treat any kind of collection of objects as a single entity. Sometimes you need to pick out or extract individual elements or groups of elements from a list. Set up a list of the first 10 squares (stored as v ):

Elements of lists are accessing using double square ... first through fifth elements, counting every two elements, ...

Lists are central constructs in the Wolfram Language that are used to represent collections, arrays, ... Multiply each element in the list by the scalar k:.

Parts of Lists. Part lets you pick out an element of a list. [ [ ... ]] is an alternative notation. You can ask for a list of parts by giving a list of part numbers. ;; lets you ask for a span or sequence of parts. Let ’ s now talk about lists of lists, or arrays. Each sublist acts as a row in the array.

Elements of Lists. The Wolfram Language provides a carefully chosen set of functions for accessing elements of lists using either indices or positions, or using patterns or criteria for their values. list [ [...]] ( Part) — parts of lists, resettable with =.

In the Wolfram Language, mathematical functions are automatically taken to be "listable", so that they are always applied to every element in a list.

Learn to pick out elements from a list or array. Find the position of a select element. Replace parts of a list ... Each sublist acts as a row in the array.
