Hello,
I have a problem with the greek letters in the line below. How can i insert the greek letters and also multiply them with each other the same time?
rs=(kB*T)/(4*π*η*D0);
Thank you!

As far as I know you cannot use special symbols in matlab. You have to write them as pi and eta

Indeed, not allowable, not just what you know... :)
variable-names has the rules.
It doesn't seem as though there really is any direct reason the character set couldn't be extended, but never seems to occur. Of course, there are potential issues with internationalization and not all character sets are the same, but doesn't seem insurmountable.

syms kB T D0
Pi = evalin(symengine, '`π`');
nu = evalin(symengine, '`η`');
rs=(kB*T)/(4*Pi*nu*D0);
rs =
(T*kB)/(4*D0*`η`*`π`)
... Just don't ask to symvar(rs)
