Is there a way, for example, given two numbers a and b I can either use a function or define a symbol, say %, such that a%b = (a*b)/(a+b)?

Aleem - I think the easiest approach would be to create a function. It would take the a and b as inputs, the function body would be your above equation, and the output parameter would be the result. Is there a reason why you want to create a function rather than just writng the above where needed?

I managed to use a function handle that takes two variables as input and returns xy/(x+y), although I was curious to know if this could be done by defining a symbol to perform the operation.
