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!

Undefined function 'secs2hms' for

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