from what I've seen on the stream: holy shit
but I can't get this to run as it wants 128G of RAM, not even the uni servers have this :/

Does this really need 128GB of memory?
No, it does not (should not) need 128G of memory, maybe a new unknown issue? Send more details e.g. through GitHub and I'll investigate. It has known issues on 4K monitors though; for that, try changing to a lower resolution before running.
Immediately upon invocation:
After disabling "Limit the maximum array size to a percentage of RAM"
I have 32GB physical available and several more in swap. My main monitor is 2560x1440. I'll see if messing with that changes anything.

Requested 17094516516x1 (127.4GB) array exceeds maximum array size preference. Creation of arrays greater than this limit may take a long time and cause MATLAB to become
unresponsive. See array size limit or preference panel for more information.

thumb for memory
Tried it on 1366x768 (via X11 forwarding to the uni servers), R2019a. They have 16G RAM and 8G swap, Ubuntu 18.04.3 LTS.
I suspect this is a character encoding issue on linux; song data is in strings and a char 255 in wrong place would result an array of 2^255 elements getting allocated... When I have time, I'll provide a fallback version that doesn't use strings, let's see if it helps.
noby uses Windows
really fascinating platform choice and execution, thanks for providing the source too!
(i'd try running this myself but i suspect my university ssh account is long dead)

Can't test on anything, but this is amazing anyway
To people having issues with excessive memory usage: it is due to MATLAB character encoding being other than 'windows-1252'. As a quick fix, run
Code:
before starting the intro.feature('DefaultCharacterSet','windows-1252')The above is indeed the fix it needed.
Really wonderful stuff! Haven't seen something like this since... the early 2000s days of replay, ephidrena and others. Pleasant colors, simple but beautiful music, just bits of matter living in a digital space. Put me in a really good mood.
The viability—or even validity—of Matlab is of course questionable, especially considering is this an intro at all. But then again all demos are essentially just binaries executed against some kind of an abstract machine description, and maybe Matlab can be one of those too. At least the results speak for themselves.

Like this !
Great style, music, sync, and insane platform!
Yep, I can confirm it works with that workaround now. (Except it's at <1 FPS because X11 forwarding... will try on campus after the weekend.)
old good Replay style
Thumb up for atmosphere of the beginning of 2000 :)
Also if browsers are a valid platform for 4ks, Matlab is too, imo.

valid platform
imho there is only one way to confirm the validity: "can someone make a demo for it?" followed by "has there been a demo for it?" :-)
anyway, do pouet platforms need to be subdivided now? :-)
and yes, nice demo!
Update: the memory allocation crash should now have been fixed. Fixed version can be downloaded from GitHub. The fix also saved some bytes, so porocyon & noby got their names into the greets for filing the bug report.
Nice!
great intro & very refreshing to see this 2000's aesthetics :)
(also, very nice job with Soundbox)

best matlab 4k i ever saw!
I would like to say that the "2000's aesthetics" is very much intentional, but part of it is simply due to MATLAB having no programmable shaders, or not even blend modes... There is just flat & gouraud interpolation, with some specular-ambient-diffuse lighting model for the vertices. Blending is just alpha blending, but at least it has depth peeling so early 2000's issues with correct z-ordering for alpha blending are not there :) So those are the biggest handicaps.
On the positive side, MATLAB has no namespaces. For anything serious, that is almost unbearable, but it is great for size coding: no lines wasted for imports. Standard library also comes with bunch of nice functions for demo coding, for example spline interpolation, audioplayer etc... Everything is just a few lines away; the overhead for getting something on screen and playing is very minimal. And compact matrix/vector/complex number notation is of course the king.
Oh, and it ships with MRI-data of someone's brain.

Sweet indeed!
cool idea!
nice work!
Looks Like à replay démo from the golden ages
this is fab!
great aesthetics
Ambient math!
Wow, MATLAB!
a superb one
Awesome :)
great stuff
gr8
Pretty cool!
Good vibe and thanks a ton for the greetings (@__@)

The aesthetic is king. 2000's or not.
Some kind of explanation on what exactly is done would be nice. Does MATLAB just allow to define arbitrary 3D geometry and a camera and just get it rendered? Assuming yes?

nice
Early 2000s + Platform thumb
moody
Aye
Matlab 4k, just WOW :)
Nice
Cool relaxing demo for MATLAB with 128gb RAM just saw it on MDT9k
This is definitely a very good 4k intro, and the platform is an additional big plus.
yes
delicate.
Mellow
great
=)
Nice idea, very cool!
You can kind of recognize the matlab style
and it is used in a very creative way.
