| ![graphoutput][1] "[The number of k-permutations is always less (or equal) than the numer of k-tupels][2]", is a known simple truth in combinatorics: ![inequality][3] Table[n!/(n - k)! k && k > 0, {n, k}, Integers] Does anyone have... |
| All symbolic entries of the array **cArr** should be set to 0, i.e. *c(i)=0* for all *i*. Later they should be set to 7, i.e. *c(i)=7* for all *i*. Desired effect: within the **Do** -loop I need to access individual entries like *c(3)* to be 0, and... |
| m^0 should be the [identity matrix][1]. but most of my test matrices return a 0^0 Indeterminate error . m={{1,-\[Sqrt]3,0},{\[Sqrt]3,-1,0},{0,0,1}}; m^0 I am just wondering what's going on here. Where I encountered this funny... |
| Hi, beginner here, again. Thanks for looking. I would like to "partition" this list from given {1, 2, 3, 8, 4, 2, 6, 7, 3, 2, 1, 9, 8, 9, 1, 3, 1, 2, 9, 2, 8, 2, 7, 7, 1, 2, 3, 4, 3, 2, 1}; into output (for further processing), either or: ... |
| I do junior highschool 'algebra with sets' (not 'Boolean algebra' per se!). If A and B have an empty Intersection, then it follows that the **Union** of (B) **with** the (complement of A) is simply the (complement of A). Likewise, the **Union** of... |
| I made a screenshot of a typical post editor from another forum, i'm contributing member on several forums. The screenshot is self-explanatory: ![enter image description here][1] [I am trying to use *Mathematica* as substiute for my other installed... |
| I am a *Wolfram L* core **l**anguage **l**earner (and always a beginner), this is my numbered **p**roblem/question no.1, thanks for your attention. The **Thread** function looks suitable for my task: In[1]:= Thread[ f[x, { a,b,c }] ] ... |
| With Permutations(), Subsets(), Tuples() i can build nice lists without further editing/programming, they're convenient to use. With an awkward combination of three functions i can build a Mma list which is a [k-multiset][1]. I can't find a... |
| **How to import listed data from a webpage?** Since I enjoy watching professional men's tennis (ATP Tour), let's take this webpage as example, the http or https URL is: [https://www.atptour.com/en/players/andrey-rublev/re44/rankings-history][1]... |
