I may be a bit slow in the uptake. But I can't get algebraic expressions to work (on Raspberry Pi Zero W):
Now it's true that it is almost 70 years since I had algebra in school, but I don't believe my math teacher would have been amused with this answer. What did I do wrong?
Are you using square brackets for functions? For example do
You are right, I am slow. I hadn't twigged to functions requiring square brackets. Thanks.
This is great news on the Mathematica upgrade! Thank-you Alex and Stephen Wolfram! This is really great to see you support the GNU community, educators, hackers, makers, students, etc. In the long run, it can only benefit Wolfram. Glad to see that the RPi2 users were not abandoned with a one time version only. Giving the reception of the RPi2, I am hoping that the RPi Foundation will go to Armf8 or better soon. Does Mathematica run a lot faster on a cluster of 4 Rpi2's? Anyone have any experience on that?
Last week I just finished making a few images of the 11/21/15 Jessie release with all my files (I have several RPi2's at home and work), and I had a feeling that the RPi Foundation would be doing a new release around Feb., as they did last year. I was wondering if Wolfram was going to do an upgrade.
After updating the cache, can I just sudo apt-get upgrade wolfram-engine on the previous (11/21/15) release of Jessie Raspian, or do I need to start over with the new 2/3/16 Jessie Raspian release to upgrade from the 10.0.2+2015092101 Wolfram-Engine? In a previous release of Wheezy Raspian I tried to upgrade the Wolfram-Engine from a slightly earlier version, and had a problem with Mathematica hanging up after upgrading the Wolfram engine.
It is a royal pain to constantly start over and load all my software and files to a new operating system every time they have a new release of Raspian.
Im using the latest Raspbian version on a Raspberry Pi 2. My intention is to control TinkerForge Bricks and Bricklets with the available Mathematica API Bindings as described in the instructions here .
.NET/Link support is required besides further prerequisites. Unfortunately the NETLink folder in the directory /opt/Wolfram/WolframEngine/10.0/SystemFiles/Links is missing. The execution of the example coding fails. With Python it works well.
Is there any option available to subsequently add the missing ./NETLink functionality on Raspbian?
There's no option available to add functionality to the Raspberry Pi release of the product, but we could add NETLink in a future release.
Alex - does your comment suggest that there actually will be a future release of Mathematica on the RPi? The last update was a year ago, and it would be great to have some of the cool tools in 10.1/2/3 available on the RPi as well.
10.3.1 should already be up on the Raspberry Pi foundation's dpkg repository. The next update should follow in a few weeks. It's getting closer to being feature-complete with the standard workstation product but it's not quite there yet.
Thanks Alex - I checked the Raspberry Pi blog this morning and saw the announcement. I guess I needed my patience to last just one more day. Very exciting.
Is there, by any chance, news about NETLink in a coming release?
It seams, that NETLink has not been implemented in 11.0.1. I found instead the more specific TinkerForgeWeatherStationTools in the "Links" directory. It is worth to have a look at this directory, because of many additional libraries.
I am still interested in calling Node.js and Python language from within Mathematica. Might "ExternalEvaluate" be an option? Is it available on RasPi as this ist "New/Experimental"? Documentation
I configured Python according to this instructions here but was not able to connect to with FindExternalEvaluators. (I used pip install pyzmq instead of zmq package, prerequisites have been met).
The installation of Node.js failed. Find the log-file as an attachment.
ExternalEvaluate was introduced in version 11.2, so it would not be available in version 11.0.1.
