I designed a gaussian filter in Matlab with these values of sigma and mean:
sigma = 1.5040e-08;
u=0;
by usisng this line of code:
Gt = gaussmf(tt,[sigma u]);
the first element is the time axes of my signal.
Now the result is a low pass filter but I want a gaussian band pass filter, what should I do to convert my filter to a bandpass?

I find the answer of this question and writing it here in case that anyone needs it in the future:
When we think of low pass or band pass in the frequency domain, a gaussian low pass filter must just pass the low frequency infomation and what about its counterpasrt in the bandpass? that will be a shift in frequency domain around the f0. Shift in frequency domain is a multiplication in time domain(e^(-jw0t)). I did this buy multiplying my low pass gaussian filter in cos(w0t).
