Passing a function output to both objective function and nonlcon in fmincon

I am solving the optimisation of a function: f(y(x),x) with the non-linear constraint: g(y(x),x) with resect to u. Written in MATLAB as something like:

fmincon(@(x)(f(y(x),x)),x0,[],[],[],[],xlb,xub,@(x)deal(g(y(x),x),[]))

Is there any way to calculate y once per iteration? (without using globals)
