Not enough input arguments: fminbnd

Function file:

function fun = SinExample(x,x1,x2)
x1 = 0;
x2 = 2.*3.14178;
fun = sin(x);

Solution File:

x1 = 0;
x2 = 2.*3.14178;
fun = fminbnd(@SinExample,x1,x2);

I am a beginner and this is a simple example file solving for sin(x). It just says, "Too many input arguments," in line 5 i.e. "fun = fminbnd(@SinExample,x1,x2)." Tried to execute with only the function file:

function fun = SinExample(x,x1,x2)
x1 = 0;
x2 = 2.*3.14178;
fun = sin(x);
fun = fminbnd(@SinExample,x1,x2);

Error-"Not enough input arguments," in line 4 i.e. "fun = sin(x)".

Please yelp.

[KSSV]

fun = @sin;
x1 = 0;
x2 = 2.*3.14178 ;
x = fminbnd(fun,x1,x2)

Tried that! Too many arguments.

Show us the complete output of this command:

which sin -all

And please post a copy of the complete error message.

The Problem's been resolved. But, Could any of you provide me with a editor code for fminbnd sin. And What do we do if we are getting arguement errors as specified as above?

"Could any of you provide me with a editor code for fminbnd sin"

KSSV already did.

"And What do we do if we are getting arguement errors as specified as above?"

Restart MATLAB and do not name variables or functions with the names of any inbuilt MATLAB functions.
