I am doing symbolic computation. I am looking to define greek letters as syms
syms x y z t \epsilon
syms u(x,y,z,t) v(x,y,z,t) w(x,y,z,t) \rho(x,y,z,t)
somthing like this, but this is giving error.

Ran in:
They are defined as such, but you will need to use commands to display them -
syms x y z t epsilon
syms u(x,y,z,t) v(x,y,z,t) w(x,y,z,t) rho(x,y,z,t)
disp(epsilon)
ε
disp(rho)
If you want to make them appear as greek alphabets directly when used as a variable, the only option is to use a LiveScript.

Ran in:
MATLAB does not permit using greek characters as variable names.
\ expressions cannot be used as variable names.
However if you use a Symbolic Toolbox syms that is the name of a Greek letter without the \ and you are using Livescript and the symbol appears as part of an expression being displayed, then it will be rendered as Greek... but only on the right hand side
syms beta Gamma
alpha = beta + Gamma
alpha = 
in Livescript this would display the beta and Gamma as Greek but not the left side alpha
For more obscurity and hacks see https://www.mathworks.com/matlabcentral/answers/463174-typing-an-equation-in-matlab-with-greek-letters#answer_375925
Note: this special formatting of names of Greek letters does not work in the Command Window -- only in Livescript (or MATLAB Answers or MATLAB Online)
