I would like to obtain the distance with respect to the centriod (both distances 97.2 and 152.78) as shown in the figure. The centroid already obtained by the following commands (255.55) but I would like then to calculate the distance 247.22-(100+50)= 97.2
and for the bottom equal to (300+100)-255.55=152.78
So I would like my output to be =[97.2 247.22 152.78]
I would like to have a commands which works for different number, hope you get the idea nd could help me
function [Ybar]=y_bar_calculations(l)
l=[50 200 300];
for i=1:length(l)
if i==1
Ybar_Pre(i)= l(i)/2;
Ybar_Pre(i) = sum(l(1:i-1)) + l(i)/2;
Ybar(1:length(l),1)= Ybar_Pre(length(l):-1:1);
% OUTPUT SHOULD BE [97.2 247.22 152.78]

Rik ? Can you please help?

The origin is not a number, it is a position.
Now define your inputs explicitly: mark points with letters and list all letter-to-letter distance you know as input. Then point out what you need as output, putting additional letters if needed.
Now that you have your geometric problem defined you can start writing the algebra: which values do you need subtract from which other value?
Only then can you write it as a function.
