| Simple text works lm = {{{1, 2}, {4, 5}}, {5}, {1, 2, 3, 4}} SetDirectory["H:\\"]; Put[lm, "test.txt"] newlm = |
| The answer to an alternative notation is contained in package Notation`. One can turn subscript into a representation of the [[ i ]] notation. It doesn't make code entry easier but it does make it readable and compact. (The biggest problem is... |
| Syntax clumsy but at least the formula is built-in. a = Quantity[4*10^14, "Hz"]; b = Quantity[273, "Kelvin"]; FormulaData[{"PlanckRadiationLaw", "Frequency"}, {QuantityVariable["\[Nu]","Frequency"] -> a, ... |
| The background is that I have been using DictionaryLookup[] to generate data for solving word puzzles. For example all words with doubled letters with length >6. Mathematica returns a list of 18000+ words at a rate of ~7 micro-seconds/word. ... |
| Or if there's no transformation at all: {x -> a, x -> b, x -> c}[[All, 2]] {a, b, c} |
| Capitalize log - should be Log. |
| It (copy - paste) works on windows. Captured screen to notebook then captured image of that. Click on the image and a toolbar for transformations pulls down. `Import["file"]` will do the same at the cost of an input line. ![enter image... |
| One of the things to learn about Mathematica (Wolfram) is to search the documentation for functions that may simplify your work. Try *guide/NumberTheoreticFunctions* in the documentaion. There you'll find `Divisors[]` and `DivisorSum[].` A number... |
| I found that `CellPrint` does not group the output as `Print` does. The result is that to delete many many cells it's easier to copy the code and delete the entire notebook. |
| In my use of Datasets I've noticed Mathematica does a decent job of displaying nested data, though individual arrays are still limited to 16 values. To show more data let's build a dataset of nested data.. The inputs are the dataset to display... |
