x = linspace(0,10);
y = 1.5*exp(-(x-2).^2) + 2*exp(-(x-7).^2*2.5) + exp(-(x-9).^2*5);
[pks,locs] = findpeaks(y)
[maxpk,idx] = max(y)
figure
plot(x, y)
hold on
plot(x(locs), pks, '^r')
hold off
Result = table(pks(:),locs(:),(locs(:)-idx),(x(locs(:))-x(idx)).', 'VariableNames',{'Peaks','Indices','Index_Difference','X_Difference'})
.
