False result why applying interp1 function!

Hi to all,
I have data taken at non-regular intervals, and I'd like to interpolate the data to have values every 100ms.
if
17:43:08.437 > ATT_HandleValueNotification: status=0 h=45 n=3 07 C7 17
17:43:08.477 > ATT_HandleValueNotification: status=0 h=45 n=3 07 C7 17
17:43:08.497 > ATT_HandleValueNotification: status=0 h=45 n=3 07 C7 17
17:43:08.516 > ATT_HandleValueNotification: status=0 h=45 n=3 07 C7 17
17:43:08.537 > ATT_HandleValueNotification: status=0 h=45 n=3 09 C7 17
17:43:08.577 > ATT_HandleValueNotification: status=0 h=45 n=3 07 C7 17
end
My code is :
if s=data(:,3)+data(:,4)/1000; % convert to seconds+fractions
t = datenum(2014,07,18,data(:,1),data(:,2),s)*86400;
t = t - t(1);
sample = interp1(t,res(:,1:3), 0:0.01:t(end)); % i fixed a time to 100ms to obtain estimated data in this time
// end
Thanks in advance
end

@inti,
By far the best thing you can do to help us solve your problem is to give us a small piece of functioning MATLAB code (including the part that defines the data) that illustrates the problem. Otherwise, we spend far too much time guessing.
