findpeaks gives you location of the peak as well
[pks,locs] = findpeaks(PeakSig,x);
dist = locs(2) - locs(1); %or whichever two peaks you want to know about

%If y is your signal
x=10:0.1:100;
y=100*cos(x)./x;
plot(x,y)
% you have to specify what is the major peak
min_peak=2
[peaks,idx1]=findpeaks(y)
% Major peaks and indices
[major_peaks, index]=find(peaks>=min_peak)
indices=idx1(index)
%distances
distances=mean(diff(indices))
