Save ginput values under a for loop

Hi I wanted to save values obtained from ginput inside a loop and create an array with those, my for loop looks like:

for index=1:24

    figure('Position',[1 1 scrsz(3)*0.9 scrsz(4)*0.9]);

    plot(t*1000, TRnorm(:,index), 'b');

    hold on;

    plot(t*1000, TRACES(:,index)/max(TRACES(:,index)), 'k');

    plot([T(index) T(index)],[1 -1], 'r');

    title(['Shot at ',D,' m and geophone at ', num2str(x(index)),' m'])

    [B,A]=ginput;

end

So as i do get 24 images one by one and get to select a ginput point in each, it doesn't save the values in A and B. I would like to store all the values of B and A I selected in arrays, how can i do that?

Thanks!!

Just replace

[B,A]=ginput;

with

[B(index), A(index)] = ginput;

to store each pair of inputs in array elements. Ideally preallocate your arrays before the loop starts with

A = zeros(1, 24);
B = zeros(1, 24);
