How to pass constants when solving nonlinear problem using fsolve

How to pass constant's into functions when solving non-linear equations using fsolve? Currently H is defined as a constant in rootNd0.

 %%%%%
index = 1;
for H = -4:4
    r0 = zeros(1,m); % Solution Vector
    fun = @rootNd0;
    options = optimoptions('fsolve','Display','none','PlotFcn',@optimplotfirstorderopt);
    r = fsolve(fun,r0,options);
    M = 1:m;
    phi = 2*pi*M*(1+sqrt(V))/2;
    [xpos(index,:), ypos(index,:)] = pol2cart(phi,r);
    index = index + 1;
end
%%%%%
