Element[x, dom] or x \[Element] dom asserts that x is an element of the domain dom. Element[x, reg] or x \[Element] reg asserts that x is an element of the region reg. Element[x1 | x2 | ..., dom] asserts that all the xi are elements of dom. Element[patt, dom] asserts that any expression matching the pattern patt is an element of dom.

Table uses the standard Wolfram Language iteration specification. Table evaluates its arguments in a nonstandard way. Table [ expr, spec] first evaluates spec, then localizes the variable specified and successively assigns values to it, each time evaluating expr.

This is an alternate method, but I rather prefer kale's: FindCol[t_, n_, col_] := t[[Position [t, n][[1, 1]], col]] FindCol[data, 0.049, 3] (* -0.439999 *).

In the Wolfram Language , many kinds of data are stored in tables or lists. ... Tables in the Wolfram Language can contain arbitrary elements. Make a Table ...

This gives a table of the first five powers of 2: Copy to clipboard. ... This picks out elements indicated by a 1 in the second list: Copy to clipboard.

Here ’ s how this works. To make the first element of the list, n is taken to be 1, so a [n] is a [1]. To make the second element, n is taken to be 2, so a [n] is a [2], and so on. n is called a variable because it ’ s varying as we make the different elements of the list. With Table, you can make tables of anything.

Jun 15, 2020 · These are given data, in a triplet form whose first, second and third elements are respectively x,y and z. All I want to do is ,for a given x, to sum z's for different y's and, for a given y, sum z's for different x's.

The Wolfram Language has many matrix operations that support operations such as building, ... Use Part to go to the first row and take the second element:.

Table reevaluates RandomSample[{1,2,3,4},2] for each element in the list, ... "Linear Algebra in Mathematica" discusses many other matrix operations that ...

You can pick out elements from a matrix just like you would from a list. Set up a 5×5 matrix of integers:.

(List) — specify a list explicitly. Table — make a table of values of an expression ... Nothing — an element automatically removed from lists.

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 ):

Jul 13, 2015 · and I want to find the right element in the table. For example each row has three columns and I want to specify the value in the first column while the program should return the other two. Example: If I insert value 0.049 this is element {0.049, 0.639568, -0.439999} in the table and I want the computer to return me values 0.639568 and -0.439999.
