I made a video testing Mathematica (from Wolfram) on Raspberry Pi in PAL. I also start some of the alternatives e.g. wxMaxima, QtOctave (similar to Matlab), and ROOT (from CERN). In the end I rotate the 3D-plot in Mathematica.

Such as shame that your video at 360p doesn't have enough detail to see what you're typing on some of the screens (especially the white text on a black background is impossible to see).

I uploaded it in 720x576 (576p25) and it became 360p. Normally I upload in 640x480 (480p25) and then it becomes 480p. I'm no YouTube expert but it seems I should stick to 640x480. It's also possible in my video recording software to increase the quality and I should try that. I tried to download using youtube-dl in order to get the original video back but it gave an error.

I've found out now how to increase the font-size in each of the programs so future videos should be more readable.

What I wrote in the video:

In Mathematica (end a line with Shift+Enter):

Code: Select all

2+2
N[Log[4 Pi],40]
x^4/(x^2-1)
Integrate[%,x]
Plot3D[Sin[x y],{x,0,Pi},{y,0,Pi}]
Plot[Sin[x^3],{x,-2,2}]

These examples come from the book "Mathematica – A System for Doing Mathematics by Computer" (1988) by Stephen Wolfram.

In wxMaxima (end a line with Shift+Enter):

Code: Select all

2+2

In QtOctave (end a line with Enter):

Code: Select all

2+2

In ROOT (end a line with Enter):

Code: Select all

2+2
for(int i=0;i<0;++i) printf("%d\n",i);
