Alternative to rhs function

Good dusk,

I have a symbolic equation and I want to assign the rhs of it to a variable (this rhs will be a number, but I do not know it a priori), but as I am using matlab R2016b I do not have the rhs function at my disposal.

var = rhs(eqn)

The above line is what I want to do.

What could be a way to do this in my current version?

Best regards.

Well, I found out a solution and it is quite embarassing telling what it is.

I just assigned the rhs of the equation to an auxiliary variable, and then I just did

var = auxiliary_var

It is not an alternative to rhs function, but solved my problem.

Sorry for being stupid.
