In Mathematica, most of what you do is based on expressions. Expressions naturally have the tree structure. For depth-first traversals (which are probably most common), you can then use functions like Scan,Map, Cases etc. The difference w.r.t the more traditional languages is that there is no simple way to preserve the identity of individual node … Read more
I use Mathematica to take lecture notes in real time without any major issues (while the proud TeX guys struggle hard to keep up 🙂 ). I have also used it for most math-related homework/assignments I wrote during past two and half years on university. Before you start, you may want to look at some … Read more
Mathematica evaluates expression once, then returns the expression unevaluated [closed]
Whilst this may not be a better way, an alternative approach to circumvent the need of J/Link would be to set up an intermediate CGI script to translate the request from GET to POST for you. This script file would sit on an accessible server, it would take the specified GET query, make a POST … Read more
A more practical difference between Block and Module can be seen here: Module[{x}, x] Block[{x}, x] (* -> x$1979 x *) So if you wish to return eg x, you can use Block. For instance, Plot[D[Sin[x], x], {x, 0, 10}] does not work; to make it work, one could use Plot[Block[{x}, D[Sin[x], x]], {x, 0, … Read more
To show how to create documentation that incorporates to the Documentation Center we will create a package that contains very simple functions and its documentation. Lets call our package SOPackage. This package will be stored in a folder of the same name and such folder should be stored in either $BaseDirectory or $UserBaseDirectory$. The SOPakage … Read more
