Examples: • the number 1 here: A1 (pronounced "A sub 1" or just "A 1") • the letter m here: xm (pronounced "x sub m" or just "x m") Often used when we have a list of values. Example: Average = (x1 + x2 + x3 + ... + xn)/nthe Subscript expressions): NDSolve [ {y' [x]==-\ [Rho] y [x],y [0]==y0,I \ [HBar] y' [x]==\ [Epsilon] y [x],y [0]==y0,y'' [x]+2 \ [Rho] y' [x]+k^2==0,y' [0]==g0},y,x] Second,it doesn't make sense to ask for a NUMERICAL solution, with NDSolve, unless you specify an interval: the last argument should not be x but rather something like {x,0,2}.where Abs is Mathematica's function for an absolute value. Also, the t_ means any variable, and := is the form of equal sign used in function definitions. The /; imposes the conditions under which the definition applies. For n = 5 and Z0 = 100, this looks like:-0.4 -0.2 0.2 0.4 t-1-0.5 0.5 1 f+ t/ Increasing n to 10 increases the number of cycles: For example, option + 208C will make subscript equal to symbol like ₌.

Creating superscripts and subscripts in Mathematica with the keyboard and Classroom AssistantNov 11, 2013 · This is why it is important to include the subscript \(F\) in \(G_F\). Furthermore, one should not confuse the two different senses of “undecidable” in this context. On the one hand, a particular sentence, like the Gödel sentence, may be undecidable in the sense of being independent, i.e., neither provable not refutable in a chosen system. Although nowadays the vast majority of what the Wolfram Language (and Mathematica) does isn't what's usually considered math, we still put immense R&D effort into pushing the frontiers of what can be done in math.

Note for those who are not english speakers, Koolaid is a flavored sugar drink mix for children and "drinking the Koolaid" is a slang term for having lost ...Aug 25, 2022 · There is a well understood convention that putting a numeric subscript to the right of a digit string means "interpret this digit string using place-value notation in the given base". The two meanings are exactly the opposite of one another. First, because \stretchint and \scaleint take a size argument, they have to be enclosed in braces for the subscript and superscript to understand to what it is actually referring. In addition, negative space has to be added to the subscript to account for the slant of the integral operator. Another common syntax mistake is the naming of built-in Mathematica functions. Mathematica functions are always capitalized. Forgetting to capitalize a Sin[x] or an Exp[y-1] will cause errors because Mathematica will not recognize them. Defining Functions: Defining a new function in Mathematica is also slightly tricky, syntax-wise.BernDirac.

Once you have typed the command, hold shift down and then hit enter. Hitting shift and enter simultaneously allows you to enter the command, but just hitting enter has no effect. Subscripts can be very helpful when differentiating between variables.ü 1.1.1 First-Time Users of Mathematica 7 Launch the program Mathematica 7 on your computer.

Share, Improve this answer, answered Jul 9, 2016 at 14:51, mikado,It is a syntax. In the function arguments int (&myArray)[100] parenthesis that enclose the &myArray are necessary. if you don't use them, you will be passing an array of references and that is because the subscript operator [] has higher precedence over the & operator. E.g. int &myArray[100] // array of references A matrix is an array of numbers arranged in rows and columns. In Mathematica, matrices are expressed as a list of rows, each of which is a list itself.It means a matrix is a list of lists. If a matrix has n rows and m columns then we call it an n by m matrix. The value(s) in the ith row and jth column is called the i, j entry.. In Mathematica, matrices can be entered with the { } notation ...The Mathematica package LinKnot is a combination of two packages. The first, "Knot2000" was written by M. Ochiai and N. Imafuji.
