Matlab è un software di calcolo matriciale e simulazione di MathWorks, vedere in sitografia una interessante presentazione sulla storia di questo software. Le istruzioni seguenti sono per la versione R2018a. Installare il software dai 2 DVD.

Su slackware (Fri Feb 5 21:18:59 UTC 2021) c'è un problema con l'esecuzione di MATLABWindow

/opt/MATLAB/R2018a/bin/glnxa64/MATLABWindow
/opt/MATLAB/R2018a/bin/glnxa64/MATLABWindow: error while loading shared libraries: libselinux.so.1: cannot open shared object file: No such file or directory

Questo si risolve si se si ha Steam copiando il file libselinux.so.1 in MATLAB

cp /home/gperon/.local/share/Steam/ubuntu12_32/steam-runtime/amd64/lib/x86_64-linux-gnu/libselinux.so.1 /opt/MATLAB/R2018a/bin/glnxa64/

A questo punto un altro errore si presenta

/opt/MATLAB/R2018a/bin/glnxa64/MATLABWindow
/opt/MATLAB/R2018a/bin/glnxa64/MATLABWindow: symbol lookup error: /usr/lib64/libpango-1.0.so.0: undefined symbol: g_ptr_array_copy

Per questo si devono usare le librerie di sistema e non quelle fornite con MATLAB

cd /opt/MATLAB/R2018a/cefclient/sys/os/glnxa64/
mkdir out
mv libgio-2.0.so* out/
mv libglib-2.0.so* out/
mv libgmodule-2.0.so* out/
mv libgobject-2.0.so* out/
mv libgthread-2.0.so* out/

Correggere anche un link errato:

cd /opt/MATLAB/R2018a/bin/glnxa64
ln -sf libSDL2-2.0.so.1 libSDL2.so

A questo punto i link ci sono tutti

E finalmente tutto dovrebbe funzionare :)

La finestra dell'help rimane bloccata, non carica il contenuto e blocca tutte le altre finestre di MATLAB. Per risolvere il problema impostare il browser basic alla riga di comando

>> webutils.htmlrenderer('basic');

su monitor 4K la visualizzazione potrebbe risultare difficile da leggere essendo font e icone troppo piccole. La soluzione è eseguire dalla console di MATLAB

>> s = settings;s.matlab.desktop.DisplayScaleFactor
>> s.matlab.desktop.DisplayScaleFactor.PersonalValue = 1.5

la modifica richiede il riavvio di MATLAB, adesso dovrebbe visualizzarsi in questo modo

Anche SIMULINK potrebbe apparire piccolo nelle finestre, in questo caso usare Ctrl + +. Le finestre dovrebbero apparire così
