How to align the center of mass of two density functions?

2 views (last 30 days)
Dear all,
I have two density functions which I would like to align their x-axis.
I was thinking to align then using the barycenters but I don't know how to do it in matlab.
I would like to do this to multiply later these two density functions.
Can anyone give me a clue on this?
Thank you in advance

In the attached file you may find two matrices. These matrices represents an area.
What I need to do is:
- to calculate the pdf of both matrices. For that I'm using the following code:
Na=histcount(a,'normalization','pdf');
Nb=histcount(b,'normalization','pdf');
Now I want to align both distributions according to their center (barycenter).
Thank you.

xa=1:length(Na);
xb=1:length(Nb);
Nb=Nb + trapz(xa,Na.*xa) - trapz(xa,Na.*xa);

Hello @Catalytic, thank you for your help, however I'm not understanding why you sum and subtract
trapz(xa,Na.*xa)
