Warning: Matrix is singular, close to singular or badly scaled.

I am trying to draw a bifurcation diagram. The code gives me the following warning:

Warning: Matrix is singular, close to singular or badly scaled. Results may be inaccurate. RCOND = NaN. 
> In ode15s (line 589)
> In NewBifur3 (line 21)

Could you please help me to fix it?

Usually when I see that, I think it means I need to normalize (scale) my data.

Check the second column of solution matrix. It is zero throughout. That's why you got the warning. It depends on the parameter value also. When you change those value result will also change.
