Error: Not Enough Input Arguments

Im not that experinced in matlab yet, and Im facing a problem. When I write roots command like that:

roots([3 -2 -4])

or

p = [3 -2 -4];

roots(p)

Whenever I run the program I get the following:

Not enough input arguments.

Error in roots (line 2)

Delta = b^2 - 4*a*c ;

Error in Untitled3 (line 1)

roots([3 -2 -4])

Once, I tried to reproduce the same error, I could not

>> p = [3 -2 -4];
roots(p)
ans =
    1.5352
   -0.8685

One Suspect: Is there any other file name as roots.m in the same working directory?

Oh yeah .. I had a function called roots. It is probably why the command was not working.

Thanks alot!
