how can I compare two columns from a differente table that are similar but no equal and then take the difference?

I want to sets of data, once was talking let's say one year ago, and the other one is recently, I would like to now the delta between the values but for the second set there are also new values, I tried doing something like this

clear all
clc
format short

addpath('Function')
DataFolder='Data';

%% Superstructure 
[T1] = importfileC('Data\data_1.csv', 2, 7); %Importing file from a function created in matlab
[T2] = importfileC('Data\data_2.csv', 2, 8);

% T = [T1; T2];  %note the semicolon for vertical concatenation
% %or
% T = vertcat(T1, T2);

for i=1:length(T2.xmin)
    if abs((T1.xmin(i)-T2.xmin(i)) < 0.50) || abs((T1.angle(i)-T2.angle(i))) < 5.0 
            
        T.delta(i) = abs(T1.length(i) - T2.length(2));
    end
end

It is a triple conditional with an range, if the condition are fullfil then the next step is calculate the delta of the different longitudes

T1 T2

can arrange them in a horizontal position for the corresponding value? I mean save it in another table?

I also was thinking in create a zero matrix for the maximum size of the column but I don't know then how to put the delta value

Some ideas? thank you in advance

Here is my idea

if length(T2.min) > length(T1.xmin)
    T = T1;
else
    T = T2;
end

for i=1:length(T.xmin)
    if abs((T1.xmin(i)-T2.xmin(i)) < 0.50) || abs((T1.angle(i)-T2.angle(i))) < 5.0             
        T.delta(i) = abs(T1.length(i) - T2.length(2));
    end
end

hello, thank you for replying, at the end I put it in a double loop

for i=1:length(T1.xmin)
    for ii=1:length(T2.xmin)
    end
end

and saving in the first table, thank you so much
