How can I reduce the for loop number?

How can I express these two for loops using only one single for loop?

x_data = [2 6 7 9; 4 9 11 14];

y_data = [8 10 16 31; 15 18 21 24];

for i = 1:length(x_data)

x(i) = [sum((x_data(1,i))-(x_data(2,i)))].^2;

i = i+1;

end

disp(x)

for j = 1:length(y_data)

y(j) = [sum((y_data(1,j))-(y_data(2,j)))].^2;

j = j+1;

end

disp(y)

See DGM's answer for the correct MATLAB approach.

x_data = [2 6 7 9; 4 9 11 14];
y_data = [8 10 16 31; 15 18 21 24];
x = zeros(size(x_data)) ;
y = zeros(size(x_data))
for i = 1:length(x_data)
    x(i) = [sum((x_data(1,i))-(x_data(2,i)))].^2;
    y(i) = [sum((y_data(1,i))-(y_data(2,i)))].^2;        
end
disp(x)
disp(y)

Hi, thank you for your response. Unfortunately, your code creates some additional rows. However, if I comment out these two lines -

%x = zeros(size(x_data));

%y = zeros(size(x_data));

then it shows the result that my previous code showed!

No loops necessary.

x_data = [2 6 7 9; 4 9 11 14];
y_data = [8 10 16 31; 15 18 21 24];
x = diff(x_data,1,1).^2

x = 1×4

4 9 16 25

y = diff(y_data,1,1).^2

y = 1×4

49 64 25 49

Hi! thanks! I actually first time learned about the function "diff". I guess this can potentially be a very powerful function!
