How do i use greek symbols?

I need to put this ecuation in my live script ρ=1015. If i use the insert ecuation option it doesn`t run it,and i can t use latex by itself. How do i create the ρ variable ?

Can't you just live with rho?

Can`t you use your time better than posting an useless comment? I needed the symbol for specific reasons,and not everyone is an expert in MatLab.

I'm ever so sorry for making you that upset. I will continue to walk dangerously close to that level once again though: One of the first "rules" of programming i learnt was KISS - which can be expanded to "never ever make things more complicated than necessary". In this situation transcribing ρ as rho has been sufficient for every situation I've been in where both I and the intended audience would've preffered ρ. If your audience is so pernickety that they cannot accept that I certainly do not envy you.

Variable names must satisfy certain rules in MATLAB. "A valid variable name starts with a letter, followed by letters, digits, or underscores. MATLAB® is case sensitive, so A and a are not the same variable. The maximum length of a variable name is the value that the namelengthmax command returns."

ρ fails the first of those rules, that the variable name starts with a letter. As @Bjorn Gustavsson suggested, use rho or perhaps p as your variable name.

Thank you !
