i am getting not enough input arguments error for the below code

function dx = m(t,x)

dx=zeros(4,1);

dx(1) = -(1/(8200*47*1e-9))*x(2);

dx(2) = (((x(3)-x(2))/2000) -(0.667e-3 + 0.029e-3*x(1).*x(1)*3.*x(2)))/6.8e-9;

dx(3) = ((x(2)-x(3))/2000 - x(4))/68e-9;

dx(4) = x(3)/18e-3;

[t,x] = ode15s(m,[0 50],[0 0.11 0.11 0]);

plot(x(:,2),x(:,3))

my error is like

Not enough input arguments.

Error in m (line 4)

dx(1) = -(1/(8200*47*1e-9))*x(2);

Error in untitled4 (line 3)

[t,x] = ode15s(m,[0 50],[0 0.11 0.11 0]);

[t,x] = ode15s(@m,[0 50],[0 0.11 0.11 0]);
plot(x(:,2),x(:,3))

function dx = m(t,x)
    dx=zeros(4,1);
    dx(1) = -(1/(8200*47*1e-9))*x(2);
    dx(2) = (((x(3)-x(2))/2000) -(0.667e-3 + 0.029e-3*x(1).*x(1)*3.*x(2)))/6.8e-9;
    dx(3) = ((x(2)-x(3))/2000 - x(4))/68e-9;
    dx(4) = x(3)/18e-3;
end
