MATLAB: How to get multiple Greek subscript symbols in the symbolic expression

Question

I would like to create a variable that has multiple greek subscript letters. The following is straightforward enough with Latin letters, but the syntax does not translate when using Greek letters:

K_ab := Symbol::subScript(K, ab)

Answer 1

This can be done by using the . (dot) operator or __CONCAT function in the MuPAD Notebook interface or by using the delimiters for greek symbols as outlined in the following examples:

Option 1 - Using the . (dot) operator:

K_delta_h := Symbol::subScript(K, Symbol::Delta . Symbol::Omega)

Option 2 - Using the __CONCAT operator:

K_delta_h := Symbol::subScript(K, _concat(Symbol::Delta, Symbol::Omega))

Option 3 - Using symbol delimiters:

K_delta_omega := Symbol::subScript(K, `ΔΩ`)
