Hi am using matlab(R2007a) version.

I created a function and when I try to run it I have this Error shown up

Undefined function or method 'debit' for input arguments of type 'double'.

Here is the function am talking about

function q=debit(i)
 T=117;
 Tm=30;
 for i=0:5:T
     if 0<=i<Tm
         q=49.56*(i/2.79)^2;
     elseif Tm<i<T
         q=49.56*(8.37*i/5.58)^3;
     end;
 end;

How are you calling debit? Green "run" arrow/triangle on tool ribbon, F5 key, or typing something on the command line? What are you passing in for i? And why are you even passing in anything for i when you just redefine it as the loop index in a "for" loop? You never even do anything with the i that you passed in.

It wasn't really an "Answer" so much as questions. Questions to clarify your situation so people can figure out what you did and how to correct it so that everything will work for you as intended.
