Error :RelTol must be a positive scalar.

options=odeset('RelTol','1e-3','AbsTol','1e-4');

I am trying to plot phase portraits for a non autonomous system. The code gives me the following error: Error using odearguments (line 126) RelTol must be a positive scalar.

Could you please help me to fix it?
