How to find if a symbolic operation contains a or function?

조회 수: 1(최근 30일)
I'm trying to find if a symbolic equation has the 'or' function or not.
I have tried to do this:
syms a b
has(a|b,'or') % logical 0
has(or(a,b),'or') % logical 0
I don't know if this is a bug. Do you know other ways to do this?
Thank you
