Hi,
I get this error ,
Subscript indices must either be real positive integers or logicals. The line with this error is,
simout_diff=(simout_ps(t_plot,:,1))-(full_vehicle_data_cw(t_plot,:,1));
Please help me in resolving this error and what is meant by subscript indices?

Matlab is telling you that 't_plot' is neither an integer greater than zero nor a logical variable. Since it is interpreted as an index to both the 'simout_ps' and 'full_vehicle_data_cw' arrays, this violates one of matlab's rules. In case you meant these to be functions rather than arrays, then for some reason matlab is not recognizing them as such.

Well there's your problem. See where you set the first element of t_plot to zero? Can't do that and have t_plot as an index into an array such as full_vehicle_data_cw.

Thanks for you reply. But could you please tell if I need to define the time vector whose simulation length is 30s, how will I do that.
