How to plot parameter phase plane?

Hi, I am having the following code for plotting the phase plane between two variables x and y, however, I would like to draw for parameters, say c and m

function my_phase()
IC = [0.1 0.1];
hold on
 for ii = 1:length(IC(:,1))
     %vectorfield(@EOM,0:.1:1.8,0:0.1:1);
    [t,X] = ode45(@EOM,[0 100],IC(ii,:));
    u = X(:,1);
    w = X(:,2);
    plot(u,w,'b', 'linewidth',3)

%    plot(t,u, 'b', 'linewidth',3)
%    plot(t,w, 'r', 'linewidth',3)
 end
fsize=15;
xlabel('\itx','FontSize',fsize)
ylabel('\ity','FontSize',fsize)
grid
%quiver(X(:,1),X(:,2),u,w,'r')
end 

function dX = EOM(~, x)
dX = zeros(2,1);
u  = x(1);
w  = x(2);
k  = 3;m  = 3;c=1;
dX = [u*(1-(u/k)-m*w/(1+u));...
      w*(-c+m*u/(1+u))];
end

Any hint will be appreciated. Thank you very much, Sanaa Moussa

Phase plane is a plot of displacement vs velocity. How you want to involve c and m?

Sorry for misleading you, I want to plot the parameter plane not the phase plane, for instant between c and m.
