Mathematica Commands - IT Services Mathematica supports numerous plot types and formatting options. To create simple x-y plots you can use the Plot command, for example: Plot [ Sin [Exp [x]], {x, 0, Pi}] would plot the function y=sin (exp (x)) from 0 to pi. The command Show allows you to modify the display in a graphics window. For example, the command. Place a Legend inside a Plot: New in Mathematica 9 - Wolfram Use scaled positions to put a legend inside a plot. In[2]:= X

Find the index of the minimal element using Mathematica Open Mathematica Notebook We know that both Position and FirstPosition are designed for general pattern matching and not specifically for numbers, which means they have to take care of different cases and inevitably bring down the performance. After doing some search, I found the Ordering function quite useful. MATHEMATICA tutorial, Part 1.3: Bracketing Methods This method is called regular falsi (false position method) and it was known to ancient Babylonian mathematicians. It has also linear rate of convergence of the sequence { c n } n ≥ 0 to the null r of the function f. But beware: although the integral width b n − a n is getting smaller, it is possible that it may not go to zero. 4. Patterns and Rule-Based Programming - Mathematica Cookbook [Book] Here Position locates the items, and Extract returns them. This variation would be more helpful than Cases, for example, if you needed to know the positions as well as the items, since Cases does not provide positional information. By default, Position will search every level, but you can restrict it with a levelspec as I do here.

Mathematica position. Mathematica Position of Elements of a List that fulfill an inequality 1 The task I have is pretty simple but I can not solve it in mathematica. Given a list myList = {1, 3, 4} I would like to get the position of entries smaller than a number - say 2 in the example above. Attempts such as Position [myList, # [ [1]] < 2 &] Position [myList, # < 2 &] which would be similar to the function SELECT don't work.

Parts of Lists: Elementary Introduction to the Wolfram Language 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. 20 Jobs for Mathematics Degree Holders | Indeed.com Education requirements: A Bachelor's Degree in Statistics or other math-related or quantitative field is required, and a master's degree in a math-related field is preferred and sometimes required for a statistician position.

How to find the position of elements in a list satisfying criteria As many have pointed out, Position can be used for this, but you may want to take care since Position will quite happily go into things you might not expect it to. In [17]:= Position [Sin [ {2, 4, 6, 8, 10}], _? (# > 0.5 &)] Out [17]= { {1, 1}, {1}, {2, 1}, {3, 1}, {4, 1}, {4}, {5, 1}}

Last Position function - Mathematica Stack Exchange The FirstPosition [] function can be use to locate the first position of an occurrence in a list. For example FirstPosition [list,_?NumericQ] will find the position of the first occurrence of a number in a list. Is there a function to find the last position of a occurrence? If not perhaps someone has a clever way to do it. list-manipulation Share

Find the largest element in a list and its position? - Wolfram I normally would have thought that generating the Range list and comparing one list to the other would take extra time. Position (Position[list,Max[list]]) seems the most direct approach (and usually the one function approach is most optimized in Mathematica). Can you explain why Pick is faster? Does this mean that the code for Position needs work?
