Converts a time in seconds to a time in hours, minutes and seconds.

time_string=secs2hms(time_in_secs)
%SECS2HMS - converts a time in seconds to a string giving the time in hours, minutes and second
%Usage TIMESTRING = SECS2HMS(TIME)]);
%Example 1: >> secs2hms(7261)
%>> ans = 2 hours, 1 min, 1.0 sec
%Example 2: >> tic; pause(61); disp(['program took ' secs2hms(toc)]);
%>> program took 1 min, 1.0 secs

function time_string=secs2hms(time_in_secs)
    time_string='';
    nhours = 0;
    nmins = 0;
    if time_in_secs >= 3600
        nhours = floor(time_in_secs/3600);
        if nhours > 1
