need help to find all results in one table , or any possible form

Hello, every one

I need to calculate the equation

y=sum((x - 4).^2) / 2; for every R1 less than R2

( where x contain a, b which contains many numbers)

and , Is it possible in matlab to get the results in one table that contains all results (or something similar to the table, or any form) so that it is easy to see all the results from all loops as

R2 R1 y

(or p3 p1 y, as my code),??? therefore % I try to repeat p2 to get the suitable table , for the need for every R1 less than R2, I thought I must repeat R2 to the length(R1)

the error of my result in my code is

Unrecognized function or variable 'p3'.

Error in average (line 22)

T=table(p3,p1,y)

if any prof can help me to correct my code, thanks alot

Is this what you were trying to do?

 R1=1:1:10;
 R2=1:1:10;
 a=[22 17 20 7 33 19 8 30 4 9  36 14 12 44 40 ]';
 b=[25 18 44 26 35 33 9 44 8 22 40 15 22 50 50]';
T =[];
 for j=1:length(R2) 
    y=0;
    for i=1:length(R1) 
          if R1(i)<R2(j)  
             x=((1/2)*((b-a)*R1(i)-(b-a)*R2(j)+(b+a))); 
             y=y+sum((x - 5).^2) / 2;
             T = [T; [R1(i) R2(j) y]];
          end
    end
 end
 array2table(T,'VariableNames',{'R1','R2','y'})

ans = 45×3 table
    R1    R2      y   
    __    __    ______

    1     2       3065
    1     3     2337.2
    2     3     5402.2
    1     4       2055
    2     4     4392.2
    3     4     7457.2
    1     5     2218.2
    2     5     4273.2
    3     5     6610.5
    4     5     9675.5
    1     6       2827
    2     6     5045.2
    3     6     7100.2

    5     6      12502
    1     7     3881.2

 %or table(T(:,1),T(:,2),T(:,3),'VariableNames',{'R1','R2','y'})

Excellent work,,,yes, this is what I tried and could not

Thank you so much prof Kevin
