"Too many Input Arguments" for my ode15s

Hello,

I have a question about solving "Too many input arguments" when using ode15s. But I checked that the number of arguments is correct. Also, I don't have any other file with the same file name but different arguments. I wonder if someone could please help me out here. Thanks in advance

It looks like it can take 3 or 4 input arguments:

[TOUT,YOUT] = ode15s(ODEFUN,TSPAN,Y0,OPTIONS) solves as above with default
    integration properties replaced by values in OPTIONS, an argument created
    with the ODESET function. See ODESET for details.

You use odeset() to create options, but you don't pass in options - you pass in a whole bunch of other arguments: mu,DOBu,OBu,BLTGFB1, etc.. Why? Why didn't you pass in options?

I thought I did pass in options by setting [TOUT,YOUT] = ode15s(ODEFUN,TSPAN,Y0,OPTIONS), I'm sorry but I don't quite get it, I also looked up online, but I haven't been able to figure out how to pass in options. Could you please explain more? Thanks!

I haven't used the function ever - all I did was notice that you had way more than 4 inputs so that's why it's complaining. Sorry I can't help more but I've never used that function.

it's interesting because once i had less inputs (but still >4, i had 11 back then), no problem at all running the code, all I did was just added some more inputs based on my need, but i got this error stating that i have too many input arguments. And I am not familiar with options created by odeset. So I looked up this page, http://www.mathworks.com/help/matlab/ref/odeset.html but still I am confused how to fix the problem. Thank you anyway! I hope someone else could help me out here.
