MATLAB: Constraining inputs to a maximum radius within fmincon objective function

fminconoptimization

I am trying to optimize an objective function of a 5D circle
c=[1,2,3,2,1];
r=[0,0,0,0,0] % begin from origin
maxRadius=3;
fun = @(x) -sqrt(c.*(r+abs(x)).^2); % Negative to make minimal
% Such that:
sqrt(sum(x.^2)) <= maxRadius
I'm getting hung up on the constraint on x… Where can I plug this in to fmincon? is fmincon the appropriate solver for this?

See the documentation for nonlinear constraints and, if necessary, the Getting Started example showing how to include the constraint in a call to fmincon.
