Mathematica Find Closest Value In List

Mathematica Find Closest Value In List - I have a large table of triplets whose structure is: list=Table[a,b, RandomReal[], a,1,100, b,1,100] I would like to search through the list by looking for the closest entry labeled by a,b to a given input x,y and return the associated third item in the triplet. To give an example, if I have For example I want to find out if the number 430 falls between the two values I can see with eye that it falls between 494 5 399 5 but how do I write the code in such a way that it tells me if 430 falls between 494 5 399 5 and if 430 falls between 494 5 399 5 I want to find out the location of 494 5 399 5 in the list too

I have a large 2d array of infinite precision named "data" of x values and y values. I am using Nearest to find the y-value closest to a specified number, say 0.00064. closestY = Nearest[data[[All,2]],0.00064] closestY = 0.000639` Now, I intend to find the position of this value in the list so I can find the corresponding x-value like so: Searching by closest and position I wasn't able to find an answer—but found Nearest by guessing. Nearest, however, returns the closest number itself, not the position.. After some more looking around, I learned about MapIndexed and Rules, and came up with this:. NearestPosition[haystack_, needle_] := Nearest[haystack, needle] /. MapIndexed[Rule, haystack];

Mathematica Find Closest Value In ListPosition[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. So the T C column includes all the values that start from 90 01 up to 89 2592 those in the second element of the list The DH aged DH unaged J g column would be the values that start in 0 0000159219 up to 0 0123268 those in the sixth position of the lists I hope that helps clarify it endgroup

73. Say I have a list x= 2,4,6,8,10 and I want to find out the positions of the elements that are greater than 7. Select [x, #>7&] gives the elements themselves, and Position [x,8] gives the position of the elements satisfying one of the possible criteria, but what I am looking for would be a mix of the two returning 4,5.

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.
