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. wolfram mathematica - Using Position correctly - Stack Overflow The normal way to resolve this is to compare with Equal rather than the implicit SameQ. Position [Range [-1, 1, 0.05], x_ /; x == 0.1] Share answered Apr 21, 2011 at 22:57 Mr.Wizard 23.9k 5 42 119 Thanks for the answer. I still am confused a bit. If I do FullForm@Range [-1, 1, 0.05], the corresponding value for 0.1 is 0.10000000000000009.

Finding root by False position method in Mathematica - Friendly Fun False position method is a method of finding root. For numerical analysis, here we should take two such points near root as the root stays between them. Here we will find a r oot of an equation by mathematica application. Like bisection method the f alse position method starts with two points a and b such that f (a) and f (b) are opposite signs.

Position mathematica. PDF Plotting and Graphics Options in Mathematica you conclude either I or Mathematica have messed up, look carefully at this curve; this curve goes through the points (1, 0), (0, 1), (-1, 0) and (0, -1), just as a circle does. So why does it look like an ellipse? The reason is that Mathematica' s plotting program assumes that the ratio of width to height is equal to 1/the golden ratio.

MATHEMATICA tutorial, Part 2.1: Basic Matrix Operations Mathematica multiplies and divides matrices Mathematica uses two operations for multiplication of matrices: asterisk (*) and dot (.). The asterisk command can be applied only when two matrices have the same dimensions; in this case the output is the matrix containing corresponding products of corresponding entry.

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.

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}} Position Vector - Story of Mathematics Given two points in the xy-coordinate system, we can use the following formula to find the position vector BA: BA = (x1-x2, y1-y2) Where x1, y1 represents the coordinates of point A and x2, y2 represent the point B coordinates. Note that the position vector BA represents a vector directed from point B towards point A.

Mathematica Basics--Using Variables Mathematica variables can have multiple letters in their names, and even numbers (except numbers are not allowed in the first position.) e.g. valid variable names are x, or pressure, or even sample4. A variable name like 4sample would not be allowed, however, and in fact this would be interpreted by Mathematica as 4*sample.
