error: Undefined function 'secs2hms' for input arguments of type 'double'.

I want to show my total sample time (H:M:S) in an edit box in Matlab GUI. Here is my code:

 samplingrate=200;
 totalmtime_sec=length(result)/samplingrate;
 format short;          % because totalmtime_sec = 3.000e+3 -> may give error?
 makinginteger= round(totalmtime_sec);
 makinginteger
 totalmtime = secs2hms(makinginteger);
 set(handles.edit6,'string' , totalmtime);

Although the variable "makinginteger" is 3000, I get this error:

>>makinginteger =

          3000

Undefined function 'secs2hms' for
input arguments of type 'double'.

Can anybody fix it? Thanks in advance!

If y=200, what are you expecting as result?

i checked examples for secs2hms function, when you input an integer it gives you hours, minutes and seconds in string; the problem is i am giving 3000 as an input to this function but it doesn't accept it.?

And here is the example i exactly took:

 >> secs2hms(7261)
  Undefined function 'secs2hms' for
  input arguments of type 'double'.

what is the problem with my matlab? :/

Tried creating a "secs2hms" function in current directory but still same error..

Ok, solved it. Changed directory to elsewhere and changed directory back where i created the function. Bug or glitch maybe?
