*[Cross-posted to Mathematica.SE](https://mathematica.stackexchange.com/q/218347/12)* I have a Raspberry Pi 1B with Raspbian Buster and Wolfram Engine 12.0.1. If I try to use J/Link, I get the following error message: ~ $ wolfram ... |
Mathematica 12.0 brought major positive changes to the handling of vertex and edge properties in `Graph`s. Before, almost all `Graph` processing functions discarded all properties (such as edge weights). If we took a `Subgraph` of a `Graph`, no... |
I have a text cell. I selected part of the text in the cell and made it into a hyperlink using Edit -> Hyperlink. How can I edit the link after the fact? I want to change the URL it points to. I realized that I habitually edit the cell... |
I would like to share some thoughts about a specific limitation of the Wolfram Language and ask for ideas about how problems of the sort I'll describe below could be handled better. Mathematica has many functions for discrete mathematics. A common... |
There are several pieces of functionality related to `Graph` which are unsatisfactorily documented, to the point that they are simply unusable for real work. Even after repeated requests to support, the responsible developers simply refused to... |
It's been out for quite a while now, but for those who don't know about it, I would like to announce the [BoolEval package](http://szhorvat.net/mathematica/BoolEval). *Note:* You can try a preview of the main function [from the Wolfram Function... |
Raspberry Pi users: do any of you use [IGraph/M](http://szhorvat.net/mathematica/IGraphM), a graph theory package? I am trying to decide whether it's worth continuing to produce binaries for this platform. If you use it or tried it, please... |
_This post showcases a few features of the IGraph/M graph theory and network analysis package. All examples are included in the attached notebook._ ## Installation If you do not yet have [IGraph/M](https://github.com/szhorvat/IGraphM) installed... |
Pre-process the image to obtain a reasonable skeleton. For example, img = Import["https://github.com/DeepaMahm/cytoscape/raw/master/Bagah.jpeg"] ![enter image description here][1] Notice that there is a white boundary. Crop it off,... |
EDIT 2: As noted below, the problem is now resolved. ---- EDIT and warning: If you have Mathematica on the Raspberry Pi right now, do not uninstall at this point. ---- Mathematica is no longer included in the Raspbian repositories or the... |
