Put a hat over the symbolic function/variable name

I would like to put a hat over the symbol nu as shown in the code below.

clear; clc;
syms mu nu(x) rho g theta L;
ode = mu*diff(nu(x),x,2) + rho*g*cos(theta) == 0;
bcond1 = nu(L) ==0;
dnu(x) = diff(nu(x));
bcond2 = dnu(0) == 0;
dif_Sol = dsolve(ode,[bcond1 bcond2]);
dif_Sol = simplify(dif_Sol);
% create a function nu_cap

I've never seen that done in matla-code. You most likely need to name your variables according to the matlab specification: Documentation about variable names. Why wouldn't a nu_hat name work for you? If you want to convert it to latex you might need to do some touch-up on the typesetting anyways...
