Not really sure what you want but I have this so far
s = load('Mydots.mat')
Mydots = s.Mydots;
[numDots, xy, numFrames] = size(Mydots)
for f = 1 : numFrames
thisFrameX = Mydots(:, 1, f);
thisFrameY = Mydots(:, 2, f);
plot(thisFrameX, thisFrameY, 'b.', 'MarkerSize', 15);
grid on;
xlim([-1000, 1000]);
ylim([-600, 600]);
caption = sprintf('Frame# %d of %d', f, numFrames);
title(caption, 'FontSize',16)
drawnow;
pause(0.1)
end
fprintf('Done!\n');
But do you want a volumetric image where some voxels have a gray level (and some are unassigned and thus zero)? If so, how is the gray level to be defined?
Or do you want an N-by-3 or 4 list of all the points like
x1, y1, f1, gl1
x2, y2, f1, gl2
x3, y3, f1, gl3
and so on for the other frames? This would not be a volumetric (3D) image but just a list of data. Again, how are the gray levels to be assigned?
